Information for Windows Vista users
On Windows XP, many users work with administrator rights. However, this is not desirable
from the point of view of security because it is then easy for viruses and unwanted
programs to infiltrate computers.
For this reason, Microsoft is introducing the "User Account Control" with Windows Vista.
This offers more protection for users who are logged in as administrators: thus in Windows
Vista, one administrator only has the privileges of a normal user at first. Actions for which
administrator rights are required are clearly marked in Windows Vista with an information
icon. In addition, the user must explicitly confirm the required action. Privileges are only
increased and the administrative task performed by the operating system after this
permission has been obtained.
The Avira product requires administrator rights for some actions in Windows Vista. These
actions are marked with the following symbol:
. If this symbol also appears on a button,
administrator rights are required to carry out this action. If your current user account does
not have administrator rights, the Windows Vista dialog of the User Account Control asks
you to enter the administrator password. If you do not have an administrator password,
you cannot carry out this action.
2.3 Licensing and Upgrade
In order to be able to use your Avira product, you require a license. You thereby accept the
license terms.
The license is issued via a digital license code in the form of the file hbedv.key. This digital
license code is the key to your personal license. It contains exact details of which
programs are licensed to you and for what period of time. A digital license code can
therefore also contain the license for more than one product.
If you purchased your Avira product on the Internet, or via a program CD/DVD, the digital
license code is sent to you by email.

3.7 Installation modules
In a user-defined installation or a change installation, the following installation modules can
be selected, added or removed.

Avira Free Antivirus
This module contains all components required for successful installation of your Avira
product.

Avira Realtime Protection
The Avira Realtime Protection runs in the background. It monitors and repairs, if
possible, files during operations such as open, write and copy in on-access mode.
Whenever a user carries out a file operation (e.g. load document, execute, copy), the
Avira product automatically scans the file. Renaming a file does not trigger a scan by
Avira Realtime Protection.

Avira Web Protection (for Avira Free Antivirus users, only in combination with the
Avira SearchFree Toolbar)
When surfing the Internet, you are using your web browser to request data from a web
server. The data transferred from the web server (HTML files, script and image files,
Flash files, video and music streams, etc.) will normally be moved directly into the
browser cache for display in the web browser, meaning that an on-access scan as
performed by Avira Realtime Protection is not possible. This could allow viruses and
unwanted programs to access your computer system. Web Protection is what is known
as an HTTP proxy which monitors the ports used for data transfer (80, 8080, 3128) and
scans the transferred data for viruses and unwanted programs. Depending on the
configuration, the program may process the affected files automatically or prompt the
user for a specific action.

Avira Rootkits Protection
Avira Rootkits Protection checks whether software is already installed on your computer
that can no longer be detected with conventional methods of malware protection after
penetrating the computer system.

Shell Extension
The Shell Extension generates an entry Scan selected files with Avira in the context
menu of the Windows Explorer (right-hand mouse button). With this entry you can
directly scan files or directories.

in Firefox the Avira SearchFree Toolbar must be enabled via the Add-On
Manager (does not apply to Internet Explorer). After uninstallation the search
toolbar is no longer integrated in your web browser.
Note
If you uninstall the Avira SearchFree Toolbar, Web Protection is also
uninstalled.

System Scanner
5. System Scanner
With the System Scanner component, you can carry out targeted scans (on-demand
scans) for viruses and unwanted programs. The following options are available for
scanning for infected files:

System scan via context menu
The system scan via the context menu (right-hand mouse button - entry Scan selected
files with Avira) is recommended if, for example, you wish to scan individual files and
directories. Another advantage is that it is not necessary to first start the Control Center
for a system scan via the context menu.

System scan via drag & drop
When a file or directory is dragged into the program window of the Control Center, the
System Scanner scans the file or directory and all sub-directories it contains. This
procedure is recommended if you wish to scan individual files and directories that you
have saved, for example, on your desktop.

System scan via profiles
This procedure is recommended if you wish to regularly scan certain directories and
drives (e.g. your work directory or drives on which you regularly store new files). You do
not then need to select these directories and drives again for every new scan, you
simply select using the relevant profile. See System scan via profiles.

System scan via the Scheduler
The Scheduler enables you to carry out time-controlled scans. See System scan via the
Scheduler.
Special processes are required when scanning for rootkits, boot sector viruses, and when
scanning active processes. The following options are available:

Scan for rootkits via the scan profile Scan for Rootkits and active malware

Scan active processes via the scan profile Active processes

Scan for boot sector viruses via the menu command Boot records scan... in the menu

Updates
6. Updates
The effectiveness of anti-virus software depends on how up-to-date the program is, in
particular the virus definition file and the scan engine. To carry out regular updates, the
Updater component is integrated into your Avira product. The Updater ensures that your
Avira product is always up-to-date and able to deal with the new viruses that appear every
day. Updater updates the following components:

Virus definition file:
The virus definition file contains the virus patterns of the harmful programs which are
used by your Avira product to scan for viruses and malware and repair infected
objects.

Scan engine:
The scan engine contains the methods used by your Avira product to scan for viruses
and malware.

Program files (product update):
Update packages for product updates make extra functions available to the individual
program components.
An update checks whether the virus definition file and scan engine are up-to-date and if
necessary implements an update. Depending on the settings in the configuration, the
Updater also carries out a product update or informs you of the product updates available.
After a product update, you may have to restart your computer system. If only the virus
definition file and scan engine are updated, the computer does not have to be restarted.
Note
For security reasons, the Updater checks whether the Windows hosts file of
your computer was altered, whether the Update URL, for example, was
manipulated by malware and is diverting the Updater to unwanted download
sites. If the Windows hosts file has been manipulated, this is shown in the
Updater report file.
An update is automatically performed in the following interval: 24 hours. You can edit or
disable the automatic update through the configuration (Configuration > Update).
In the Control Center under Scheduler, you can create additional update jobs that are
performed by Updater at the specified intervals. You also have the option to start an
update manually:


Adware
Adware is software that presents banner ads or in pop-up windows through a bar that
appears on a computer screen. These advertisements usually cannot be removed and are
consequently always visible. The connection data allow many conclusions on the usage
behavior and are problematic in terms of data security.
Your Avira product detects Adware. If the Adware option is enabled with a check mark in
the configuration under Threat categories, you receive a corresponding alert if your Avira
product detects adware.
Adware/Spyware
Software that displays advertising or software that sends the user‟s personal data to a third
party, often without their knowledge or consent, and for this reason may be unwanted.
Your Avira product recognizes "Adware/Spyware". If the option Adware/Spyware is
enabled with a check mark in the configuration under Threat categories, you receive a
corresponding alert if your Avira product detects adware or spyware.
Application
The term APPL, respectively application, refers to an application which may involve a risk
when used or is of dubious origin.
Your Avira product recognizes "Application (APPL)". If the option Application is enabled
with a check mark in the configuration under Threat categories, you receive a
corresponding alert if your Avira product detects such behavior.
Backdoor Clients
In order to steal data or manipulate computers, a backdoor server program is smuggled in
unknown to the user. This program can be controlled by a third party using backdoor
control software (client) via the Internet or a network.
Your Avira product recognizes "Backdoor control software". If the Backdoor control
software option is enabled with a check mark in the configuration under Threat categories,
you receive a corresponding alert if your Avira product detects such software.

Viruses and more
Dialer
Certain services available in the Internet have to be paid for. They are invoiced in
Germany via dialers with 0190/0900 numbers (or via 09x0 numbers in Austria and
Switzerland; in Germany, the number is set to change to 09x0 in the medium term). Once
installed on the computer, these programs guarantee a connection via a suitable premium
rate number whose scale of charges can vary widely.
The marketing of online content via your telephone bill is legal and can be of advantage to
the user. Genuine dialers leave no room for doubt that they are used deliberately and
intentionally by the user. They are only installed on the user‟s computer subject to the
user‟s consent, which must be given via a completely unambiguous and clearly visible
labeling or request. The dial-up process of genuine dialers is clearly displayed. Moreover,
genuine dialers tell you the incurred costs exactly and unmistakably.
Unfortunately there are also dialers which install themselves on computers unnoticed, by
dubious means or even with deceptive intent. For example they replace the Internet user‟s
default data communication link to the ISP (Internet Service Provider) and dial a costincurring and often horrendously expensive 0190/0900 number every time a connection is
made. The affected user will probably not notice until his next phone bill that an unwanted
0190/0900 dialer program on his computer has dialed a premium rate number with every
connection, resulting in dramatically increased costs.
We recommend that you ask your telephone provider to block this number range directly
for immediate protection against undesired dialers (0190/0900 dialers).
Your Avira product can detect the familiar dialers by default.
If the option Dialers is enabled with a check mark in the configuration under Threat
categories, you receive a corresponding alert if a dialer is detected. You can now simply
delete the potentially unwanted 0190/0900 dialer. However, if it is a wanted dial-up
program, you can declare it an exceptional file and this file is then no longer scanned in
future.
Double Extension Files
Executable files that hide their real file extension in a suspicious way. This camouflage
method is often used by malware.
Your Avira product recognizes "Double Extension Files". If the option Double Extension
files is enabled with a check mark in the configuration under Threat categories, you
receive a corresponding alert if your Avira product detects such files.
Fraudulent software
Also known as "scareware" or "rogueware", it is a fraudulent software that pretends that
your computer is infected by viruses or malware. This software looks deceptively similar to
professional antivirus software but is meant to raise uncertainty or to scare the user. Its
purpose is to make the victims feel threatened of imminent (unreal) danger and to make

them pay to eliminate it. There are also cases when the victims are lead to believe they
were attacked and they are instructed to carry out an action, which in reality is the real
attack.
Your Avira product detects scareware. If the option Fraudulent software is enabled with a
check mark in the configuration Threat categories, you receive a corresponding alert if
your Avira product detects such files.
Games
There is a place for computer games - but it is not necessarily at work (except perhaps in
the lunch hour). Nevertheless, with the wealth of games downloadable from the Internet, a
fair bit of mine sweeping and Patience playing goes on among company employees and
civil servants. You can download a whole array of games via the Internet. Email games
have also become more popular: numerous variants are circulating, ranging from simple
chess to "fleet exercises" (including torpedo combats): The corresponding moves are sent
to partners via email programs, who answer them.
Studies have shown that the number of working hours devoted to computer games has
long reached economically significant proportions. It is therefore not surprising that more
and more companies are considering ways of banning computer games from workplace
computers.
Your Avira product recognizes computer games. If the Games option is enabled with a
check mark in the configuration under Threat categories, you receive a corresponding alert
if your Avira product detects a game. The game is now over in the truest sense of the
word, because you can simply delete it.
Jokes
Jokes are merely intended to give someone a fright or provide general amusement without
causing harm or reproducing. When a joke program is loaded, the computer will usually
start at some point to play a tune or display something unusual on the screen. Examples of
jokes are the washing machine in the disk drive (DRAIN.COM) or the screen eater
(BUGSRES.COM).
But beware! All symptoms of joke programs may also originate from a virus or Trojan. At
the very least users will get quite a shock or be thrown into such a panic that they
themselves may cause real damage.
Thanks to the extension of its scanning and identification routines, your Avira product is
able to detect joke programs and eliminate them as unwanted programs if required. If the
option Jokes is enabled with a check mark in the configuration under Threat categories, a
corresponding alert is issued if a joke program is detected.
Phishing
Phishing, also known as "brand spoofing" is a clever form of data theft aimed at customers
or potential customers of Internet service providers, banks, online banking services,

registration authorities.
When submitting your email address on the Internet, filling in online forms, accessing
newsgroups or websites, your data can be stolen by "Internet crawling spiders" and then
used without your permission to commit fraud or other crimes.
Your Avira product recognizes "Phishing". If the option Phishing is enabled with a check
mark in the configuration under Threat categories, you receive a corresponding alert if
your Avira product detects such behavior.
Programs that violate the private domain
Software that may be able to compromise the security of your system, initiate unwanted
program activities, damage your privacy or spy on your user behavior and could therefore
be unwanted.
Your Avira product detects "Security Privacy Risk" software. If the option Programs that
violate the private domain is enabled with a check mark in the configuration under
Threat categories, you receive a corresponding alert if your Avira product detects such
software.
Unusual Runtime Packers
Files that have been compressed with an unusual runtime packer and that can therefore
be classified as potentially suspicious.
Your Avira product recognizes "Unusual runtime packers". If the option Unusual runtime
packers is enabled with a check mark in the configuration under Threat categories, you
receive a corresponding alert if your Avira product detects such packers.

A backdoor can gain access to a computer by bypassing the computer access security

Viruses and more
Boot viruses
The boot or master boot sector of hard disks is mainly infected by boot sector viruses.
They overwrite important information necessary for the system execution. One of the
awkward consequences: the computer system cannot be loaded any more…
Bot-Net
A bot-net is defined as a remote network of PCs (on the Internet) that is composed of bots
that communicate with each other. A bot-net can comprise a collection of cracked
machines running programs (usually referred to as worms, Trojans) under a common
command and control infrastructure. Bot-nets serve various purposes, including denial-ofservice attacks etc., usually without the affected PC user's knowledge. The main potential
of bot-nets is that the networks can achieve grow to thousands of computers and their total
bandwidth exceeds most conventional Internet accesses.
Exploit
An exploit (security gap) is a computer program or script that takes advantage of a bug,
glitch or vulnerability leading to privilege escalation or denial of service on a computer
system. One form of exploitation for example is an attack from the Internet with the help of
manipulated data packages. Programs can be infiltrated in order to obtain higher access.
Fraudulent software
Also known as "scareware" or "rogueware", it is a fraudulent software that pretends that
your computer is infected by viruses or malware. This software looks deceptively similar to
professional Antivirus software but is meant to raise uncertainty or to scare the user. Its
purpose is to make the victims feel threatened of imminent (unreal) danger and to make
them pay to eliminate it. There are also cases when the victims are lead to believe they
were attacked and they are instructed to carry out an action, which in reality is the real
attack.
Hoaxes
For several years, Internet and other network users have received alerts about viruses that
are purportedly spread via email. These alerts are spread via email with the request that
they should be sent to the highest possible number of colleagues and to other users, in
order to warn everyone against the "danger".
Honeypot
A honeypot is a service (program or server) installed in a network. Its function is to monitor
a network and log attacks. This service is unknown to the legitimate user - because of this
Avira Free Antivirus - User Manual (Status: 23 Sep. 2011)

Viruses and more
reason he is never addressed. If an attacker examines a network for the weak points and
uses the services which are offered by a honeypot, it is logged and an alert is triggered.
Macro viruses
Macroviruses are small programs that are written in the macro language of an application
(e.g. WordBasic under WinWord 6.0) and that can normally only spread within documents
of this application. Because of this, they are also called document viruses. In order to be
active, they need that the corresponding applications are activated and that one of the
infected macros has been executed. Unlike "normal" viruses, macro viruses consequently
do not attack executable files but they do attack the documents of the corresponding host
application.
Pharming
Pharming is a manipulation of the host file of web browsers to divert enquiries to spoofed
websites. This is a further development of classic phishing. Pharming fraudsters operate
their own large server farms on which fake websites are stored. Pharming has established
itself as an umbrella term for various types of DNS attacks. In the case of a manipulation
of the host file, a specific manipulation of a system is carried out with the aid of a Trojan or
virus. The result is that the system can now only access fake websites, even if the correct
web address is entered.
Phishing
Phishing means angling for personal details of the Internet user. Phishers generally send
their victims apparently official letters such as emails that are intended to induce them to
reveal confidential information to the culprits in good faith, in particular user names and
passwords or PINs and TANs of online banking accounts. With the stolen access details,
the phishers can assume the identities of the victims and carry out transactions in their
name. What is clear is that: banks and insurance companies never ask for credit card
numbers, PINs, TANs or other access details by email, SMS or telephone.
Polymorph viruses
Polymorph viruses are the real masters of disguise. They change their own programming
codes - and are therefore very hard to detect.
Program viruses
A computer virus is a program that is capable of attaching itself to other programs after
being executed and cause an infection. Viruses multiply themselves unlike logic bombs
and Trojans. In contrast to a worm, a virus always requires a program as host, where the
virus deposits its virulent code. The program execution of the host itself is not changed as
a rule.
Avira Free Antivirus - User Manual (Status: 23 Sep. 2011)

Viruses and more
Rootkits
A rootkit is a collection of software tools that are installed after a computer system has
been infiltrated to conceal logins of the infiltrator, hide processes and record data generally speaking: to make themselves invisible. They attempt to update already installed
spy programs and reinstall deleted spyware.
Script viruses and worms
Such viruses are extremely easy to program and they can spread - if the required
technology is on hand - within a few hours via email round the globe.
Script viruses and worms use one of the script languages, such as Javascript, VBScript
etc., to insert themselves in other, new scripts or to spread themselves by calling operating
system functions. This frequently happens via email or through the exchange of files
(documents).
A worm is a program that multiplies itself but that does not infect the host. Worms cannot
consequently form part of other program sequences. Worms are often the only possibility
to infiltrate any kind of damaging programs on systems with restrictive security measures.
Spyware
Spyware are so called spy programs that intercept or take partial control of a computer's
operation without the user's informed consent. Spyware is designed to exploit infected
computers for commercial gain.
Trojan horses (short Trojans)
Trojans are pretty common nowadays. Trojans include programs that pretend to have a
particular function, but that show their real image after execution and carry out a different
function that, in most cases, is destructive. Trojan horses cannot multiply themselves,
which differentiates them from viruses and worms. Most of them have an interesting name
(SEX.EXE or STARTME.EXE) with the intention to induce the user to start the Trojan.
Immediately after execution they become active and can, for example, format the hard
disk. A dropper is a special form of Trojan that 'drops' viruses, i.e. embeds viruses on the
computer system.
Zombie
A zombie PC is a computer that is infected with malware programs and that enables
hackers to abuse computers via remote control for criminal purposes. On command, the
affected PC starts denial-of-service (DoS) attacks, for example, or sends spam and
phishing emails.

10.1 System Scanner
The System Scanner section of configuration is responsible for the configuration of the
on-demand scan. (Options available in expert mode only.)
10.1.1 Scan
You can define the behavior of the on-demand scan routine (options available in expert
mode only). If you select certain directories to be scanned, depending on the configuration,
the System Scanner scans:

with a certain scanning priority,

also boot sectors and main memory,

all or selected files in the directory.
Files
The System Scanner can use a filter to scan only those files with a certain extension
(type).
All files
If this option is enabled, all files are scanned for viruses or unwanted programs,
irrespective of their content and file extension. The filter is not used.
Note
If All files is enabled, the button File extensions cannot be selected.
Use smart extensions
If this option is enabled, the selection of the files scanned for viruses or unwanted
programs is automatically chosen by the program. This means that your Avira program
decides whether the files are scanned or not based on their content. This procedure is
somewhat slower than Use file extension list, but more secure, since not only on the
basis of the file extension is scanned. This option is enabled as the default setting and
is recommended.

Use file extension list
If this option is enabled, only files with a specified extension are scanned. All file types
that may contain viruses and unwanted programs are preset. The list can be edited
manually via the button "File extension".
Note
If this option is enabled and you have deleted all entries from the list with file
extensions, this is indicated with the text "No file extensions" under the button
File extensions.
File extensions
With the aid of this button, a dialog box is opened in which all file extensions are
displayed that are scanned in "Use file extension list" mode. Default entries are set
for the extensions, but entries can be added or deleted.
Note
Please note that the default list may vary from version to version.
Additional settings
Scan boot sectors of selected drives
If this option is enabled, the System Scanner scans the boot sectors of the drives
selected for the system scan. This option is enabled as the default setting.
Scan master boot sectors
If this option is enabled, the System Scanner scans the master boot sectors of the
hard disk(s) used in the system.
Ignore offline files
If this option is enabled, the direct scan ignores so-called offline files completely during
a scan. This means that these files are not scanned for viruses and unwanted
programs. Offline files are files that were physically moved by a so-called Hierarchical
Storage Management System (HSMS) from the hard disk onto a tape, for example.
This option is enabled as the default setting.
Integrity checking of system files
When this option is enabled, the most important Windows system files are subjected to
a particularly secure check for changes by malware during every on-demand scan. If
Avira Free Antivirus - User Manual (Status: 23 Sep. 2011)
70
Reference: Configuration options
an amended file is detected, this is reported as suspect. This function uses a lot of
computer capacity. That is why the option is disabled as the default setting.
Note
This option is only available with Windows Vista and higher.
Note
This option should not be used if you are using third-party tools that modify
system files and adapt the boot or start screen to your own requirements.
Examples of such tools are skinpacks, TuneUp utilities or Vista Customization.
Optimized scan
When the option is enabled, the processor capacity is optimally utilized during a
System Scanner scan. For performance reasons, an optimized scan is only logged on
standard level.
Note
This option is only available on multi-processor systems.
Follow symbolic links
If this option is enabled, System Scanner performs a scan that follows all symbolic
links in the scan profile or selected directory and scans the linked files for viruses and
malware.
Note
The option does not include any shortcuts, but refers exclusively to symbolic
links (generated by mklink.exe) or Junction Points (generated by junction.exe)
that are transparent in the file system.
Search for Rootkits before scan
If this option is enabled and a scan is started, the System Scanner scans the Windows
system directory for active rootkits in a so-called shortcut. This process does not scan
your computer for active rootkits as comprehensively as the scan profile "Scan for
rootkits", but it is significantly quicker to perform.
Note
The rootkits scan is not available for Windows XP 64 bit !

Scan Registry
If this option is enabled, the Registry is scanned for references to malware.
Scan process
Allow stopping the Scanner
If this option is enabled, the scan for viruses or unwanted programs can be terminated
at any time with the button "Stop" in the "Luke Filewalker" window. If you have
disabled this setting, the Stop button in the "Luke Filewalker" window has a gray
background. Premature ending of a scan process is thus not possible! This option is
enabled as the default setting.
Scanner priority
With the on-demand scan, the System Scanner distinguishes between priority levels.
This is only effective if several processes are running simultaneously on the
workstation. The selection affects the scanning speed.
low
The System Scanner is only allocated processor time by the operating system, if no
other process requires computation time, i.e. as long as only the System Scanner is
running, the speed is maximum. All in all, work with other programs is optimal: The
computer responds more quickly if other programs require computation time while the
System Scanner continues running in the background.
normal
The System Scanner is executed with normal priority. All processes are allocated the
same amount of processor time by the operating system. This option is enabled as the
default setting and is recommended. Under certain circumstances, work with other
applications may be affected.
high
The System Scanner has the highest priority. Simultaneous work with other
applications is almost impossible. However, the System Scanner completes its scan at
maximum speed.
Action on detection
You can define the actions to be performed by System Scanner when a virus or unwanted
program is detected. (Options available in expert mode only.)
Interactive
If this option is enabled, the results of the System Scanner scan are displayed in a
dialog box. When carrying out a scan with the System Scanner, you will receive an
alert with a list of the affected files at the end of the scan. You can use the contentsensitive menu to select an action to be executed for the various infected files. You
can execute the standard actions for all infected files or cancel the System Scanner.

Note
The action Quarantine is preselected by default in the System Scanner
notification. Further actions can be selected via a context menu.
Automatic
If this option is enabled, no dialog box in case of a virus detection appears. The
System Scanner reacts according to the settings you predefine in this section as
primary and secondary action.
Copy file to quarantine before action
If this option is enabled, the System Scanner creates a backup copy before carrying
out the requested primary or secondary action. The back-up copy is saved in
Quarantine, where the file can be restored if it is of informative value. You can also
send the backup copy to the Avira Malware Research Center for further investigation.
Primary action
Primary action is the action performed when the System Scanner finds a virus or an
unwanted program. If the option "Repair" is selected but the affected file cannot be
repaired, the action selected under "Secondary action" is performed.
Note
The option Secondary action can only be selected if the setting Repair was
selected under Primary action.
Repair
If this option is enabled, the System Scanner repairs affected files automatically. If the
System Scanner cannot repair an affected file, it carries out the action selected under
Secondary action.
Note
An automatic repair is recommended, but means that the System Scanner
modifies files on the workstation.
Rename
If this option is enabled, the System Scanner renames the file. Direct access to these
files (e.g. with double-click) is therefore no longer possible. Files can later be repaired
and given their original names again.
Quarantine
If this option is enabled, the System Scanner moves the file to the quarantine. These
files can later be repaired or - if necessary - sent to the Avira Malware Research
Center.

Archives
When scanning archives, the System Scanner uses a recursive scan: Archives in archives
are also unpacked and scanned for viruses and unwanted programs. The files are
scanned, decompressed and scanned again. (Options available in expert mode only.)

Scan archives
If this option is enabled, the selected archives in the archive list are scanned. This
option is enabled as the default setting.
All archive types
If this option is enabled, all archive types in the archive list are selected and scanned.
Smart Extensions
If this option is enabled, the System Scanner detects whether a file is a packed file
format (archive), even if the file extension differs from the usual extensions, and scans
the archive. However every file must be opened for this, which reduces the scanning
speed. Example: If a *.zip archive has the file extension *.xyz, the System Scanner
also unpacks this archive and scans it. This option is enabled as the default setting.
Note
Only those archive types marked in the archive list are supported.
Limit recursion depth
Unpacking and scanning recursive archives can require a great deal of computer time
and resources. If this option is enabled, you limit the depth of the scan in multi-packed
archives to a certain number of packing levels (maximum recursion depth). This saves
time and computer resources.
Note
In order to find a virus or an unwanted program in an archive, the System
Scanner must scan up to the recursion level in which the virus or the unwanted
program is located.
Maximum recursion depth
In order to enter the maximum recursion depth, the option Limit recursion depth must
be enabled.
You can either enter the requested recursion depth directly or by means of the right
arrow key on the entry field. The permitted values are 1 to 99. The standard value is
20 which is recommended.

Heuristic
This configuration section contains the settings for the heuristic of the scan
engine. (Options available in expert mode only.)
Avira products contain very powerful heuristics that can proactively uncover unknown
malware, i.e. before a special virus signature to combat the damaging element has been
created and before a virus guard update has been sent. Virus detection involves an
extensive analysis and investigation of the affected codes for functions typical of malware.
If the code being scanned exhibits these characteristic features, it is reported as being
suspicious. This does not necessarily mean that the code is in fact malware. False
positives do sometimes occur. The decision on how to handle affected code is to be made
by the user, e.g. based on his or her knowledge of whether the source of the code is
trustworthy or not.
Macrovirus heuristic
Macrovirus heuristic
Your Avira product contains a highly powerful macrovirus heuristic. If this option is
enabled, all macros in the relevant document are deleted in the event of a repair,
alternatively suspect documents are only reported, i.e. you receive an alert. This
option is enabled as the default setting and is recommended.
Advanced Heuristic Analysis and Detection (AHeAD)
enable AHeAD
Your Avira program contains a very powerful heuristic in the form of Avira AHeAD
technology, which can also detect unknown (new) malware. If this option is enabled,
you can define how "aggressive" this heuristic should be. This option is enabled as the
default setting.
Low detection level
If this option is enabled, slightly less unknown malware is detected, the risk of false
alerts is low in this case.

Do not specify any exceptions for processes where the executable files are located on
dynamic drives. Dynamic drives are used for removable disks, such as CDs, DVDs or
USB sticks.

File objects to be omitted by the Realtime Protection
All file accesses to objects in this list are excluded from monitoring by the Realtime
Protection.
Input box
In this box you can enter the name of the file object that is not included in the onaccess scan. No file object is entered as the default setting.
The entries in the list must have no more than 6000 characters in total.
When specifying file objects to be omitted, you can use the wildcards* (any number of
characters) and ?? (a single character): Individual file extensions can also be excluded
(including wildcards):
C:\Directory\*.mdb
*.mdb
*.md?
*.xls*
C:\Directory\*.log
Directory names must end with a backslash \, otherwise a file name is assumed.
If a directory is excluded, all its sub-directories are automatically also excluded.
For each drive you can specify a maximum of 20 exceptions by entering the complete
path (starting with the drive letter). For example:
C:\Program Files\Application\Name.log
The maximum number of exceptions without a complete path is 64. For example:
*.log
In case of dynamic drives that are mounted as a directory on another drive, the alias of
the operating system for the integrated drive in the list of the exceptions has to be
used, e.g.:
\Device\HarddiskDmVolumes\PhysicalDmVolumes\BlockVolume1\
If you use the mount point itself, for example, C:\DynDrive, the dynamic drive will be
scanned nonetheless. You can determine the alias of the operating system to be used
from the Realtime Protection report file.
The button opens a window in which you can select the file object to be excluded.

Please note the further information when specifying exceptions:
In order to also exclude objects when they are accessed with short DOS file names (DOS
name convention 8.3), the relevant short file name must also be entered in the list.
A file name that contains wildcards may not be terminated with a backslash. For example:
C:\Program Files\Application\applic*.exe\
This entry is not valid and not treated as an exception!
You can locate the path Realtime Protection uses to scan for infected files in the Realtime
Protection report file. Indicate exactly the same path in the list of exceptions. Proceed as
follows: Set the protocol function of the Realtime Protection to Complete in the
configuration under Realtime Protection > Report. Now access the files, folders, mounted
drives with the activated Realtime Protection. You can now read the path to be used from
the Realtime Protection report file. The report file can be accessed in the Control Center
under Local protection > Realtime Protection.
Heuristic
This configuration section contains the settings for the heuristic of the scan
engine. (Options available in expert mode only.)
Avira products contain very powerful heuristics that can proactively uncover unknown
malware, i.e. before a special virus signature to combat the damaging element has been
created and before a virus guard update has been sent. Virus detection involves an
extensive analysis and investigation of the affected codes for functions typical of malware.
If the code being scanned exhibits these characteristic features, it is reported as being
suspicious. This does not necessarily mean that the code is in fact malware. False
positives do sometimes occur. The decision on how to handle affected code is to be made
by the user, e.g. based on his or her knowledge of whether the source of the code is
trustworthy or not.
Macrovirus heuristics
Macrovirus heuristics

Drive-by protection
Drive-by protection allows you to make settings to block I-Frames, also known as inline
frames. I-Frames are HTML elements, i.e. elements of Internet pages that delimit an area
of a web page. I-Frames can be used to load and display different web content - usually
other URLs - as independent documents in a sub-window of the browser. I-Frames are
mostly used for banner advertising. In some cases, I-Frames are used to conceal
malware. In these cases the area of the I-Frame is mostly invisible or almost invisible in
the browser. The Block suspicious I-frames option allows you to check and block the
loading of I-Frames.
Block suspicious I-frames
If this option is enabled, I-Frames on the web pages you request are scanned

10.5.2 Security
Options available in expert mode only.
Autostart
Block autostart function
If this option is enabled, the execution of the Windows autostart function is blocked on
all connected drives, including USB sticks, CD and DVD drives and network drives.
With the Windows autostart function, files on data media or network drives are read
immediately on loading or connection, and files can therefore be started and copied
automatically. This functionality carries with it a high security risk, however, as
malware and unwanted programs can be installed with the automatic start. The
autostart function is especially critical for USB sticks as data on a stick can be
changed at any time.
Exclude CDs and DVDs
When this option is enabled, the autostart function is permitted on CD and DVD drives.
