1. Introduction
This user manual offers a general overview of the tasks and detection technologies provided by AVG
2012 LinkScanner for Mac. We will briefly talk about the program installation, initial startup,
configuration and use.
AVG 2012 LinkScanner for Mac is provided free-of-charge. It is up and running immediately from
the moment of installation. All basic settings have been pre-set by the manufacturer, so most of the
time you will not have to worry about anything – just let AVG 2012 LinkScanner for Mac work in
the background and protect you without any effort on your part. However, there might be situations
where you need to adjust the program settings, or decide what to do with a virus infected file; this
manual is here to provide detailed information and assist you with any task.
1.1. What is the AVG 2012 LinkScanner for Mac?
In the last couple of years the number of malicious programs has increased dramatically. New
dangerous applications are being created every day. The majority of today's viruses, that is
spreading via Internet, is designed for financial/commercial gain. Moreover, there are far more threats
out there than plain viruses. You have probably come across the term spyware as well, however,
authors of malicious codes and dangerous websites are very innovative, and new kinds of threats
emerge quite often. Here are some of the most common:
Exploit is a malicious code that takes advantage of a flaw or vulnerability in an operating
system, Internet browser, or other essential program.
Social engineering is a common term for various techniques used to trick people into giving
away their personal information (passwords, bank account details, credit card numbers etc.).
A typical example of social engineering is phishing – an attempt to acquire sensitive personal
data by shamming a trustworthy and well-known organization. Usually, the potential victims
are contacted by a bulk e-mail asking them to e.g. update their bank account details. In order
to do that, they are invited to follow the link provided which then leads to a fake website of the
bank.
Scam can be also considered a kind of social engineering; it includes false job offers, or ones
that will abuse the workers for illegal activities, summons to withdraw a large sum of money,
fraudulent lotteries and the like.
Hoax is a bulk e-mail containing dangerous, alarming or just bothering and useless
information. Many of the above threats use hoax e-mail messages to spread.
Malicious websites are ones that deliberately install malicious software on your computer,
and hacked sites do just the same, only these are legitimate websites that have been
compromised into infecting visitors.
The AVG 2012 LinkScanner for Mac is here to protect you from all these online threats.

3.8. After Installation
The first thing you should see after your Mac OS reboots is this dialog:
It serves to inform you about a special AVG feature, allowing your AVG 2012 LinkScanner for Mac
to automatically report the threats that you encounter while surfing the web. Details about the
detected threat are sent automatically to AVG Technologies, which happens without any
inconvenience or need of any action on your part, and of course without any reference to you or your
personal data. The received data is then thoroughly analysed by our malware specialists, which
enables us to continuously improve the AVG protection for all its users. For this reason, we kindly
ask you to keep this feature activated.
However, if you don't want to enable the reporting, you can do it immediately. Clicking the Open
Preferences button takes you directly to your AVG LinkScanner Settings (more precisely the
General Settings section of the General tab). All you have to do here is to unmark the Reporting
threats to AVG checkbox.
Otherwise click the OK button to finally finish the installation process.

4. Finding your way around the AVG LinkScanner
In the AVG 2012 LinkScanner for Mac you can choose between three ways of accessing various
settings, overviews, and functions:
click the AVG 2012 LinkScanner for Mac icon in the Dock to open the Main User Interface,
where you can view current AVG protection status and access setting options for individual
components. Click to learn more about the AVG 2012 LinkScanner for Mac Main User
Interface.
click the AVG icon that is (optionally) displayed in the right part of the menu bar. Upon
clicking the icon, you get a context menu resuming neatly relevant options of the application
menus. Apart from quick access to frequently used items, the icon also indicates AVG
protection status. Click to learn more about the AVG 2012 LinkScanner for Mac icon in
the Menu Bar.
if the User Interface is active, clicking the AVG 2012 LinkScanner for Mac menu allows you
to access some basic options. Click to learn more about the AVG 2012 LinkScanner for
Mac menu in the Menu Bar.

13
4.1. Main User Interface
To access the Main User Interface, simply click the docked AVG icon.
Thereafter the Main User Interface appears:
As you can see, there are two possible views for the Main User Interface - Overview (opened by
default) and Help & Support. To switch between them, simply click the Overview / Help buttons in
the upper-right corner of the interface.
No matter which view you're currently in, you will always see your AVG protection status in the
upper part of the Main User Interface. Click here to learn more about protection statuses in your
AVG 2012 LinkScanner for Mac.
Overview
The upper section of this view displays the components of your AVG protection and whether they are
active or not. Clicking the Configure link (next to each component's name) opens its unique setting
options. AVG 2012 LinkScanner for Mac contains three components:
Secure Search - when searching the web with component on, all search results returned
from the most popular search engines are evaluated for dangerous or suspicious links. By
A V G 2 0 1 2 L inkSc anner for M ac © 2 0 1 1 C opyright A V G T ec hnologies C Z, s .r.o. A ll rights res erved.
14
checking these links and marking the bad links, this component warns you before you click
on dangerous or suspicious links, so you can ensure you only go to safe websites.
Secure Browsing - this component will block malicious content of any webpage you try to
open, and prevent it from being downloaded to your computer. With this feature enabled,
clicking a link or typing in a URL to a dangerous site will automatically block you from opening
the web page thus protecting you from inadvertently being infected.
Update Manager - this component helps you to control regular updating. Within this
component you can schedule automatic downloads of update files either from the Internet, or
the local network. Learn more about updates and why they are so important.
The bottom part of the Main User Interface shows various AVG 2012 LinkScanner for Mac
statistics:
URLs processed - total number of URLs (web addresses) that have been processed by AVG
2012 LinkScanner for Mac.
Suspicious URLs - number of URLs that have been processed and marked as risky by the
Secure Search component (low, medium, and high risk levels).
Data scanned (MB) - total size of data processed by AVG 2012 LinkScanner for Mac (in
Megabytes).
Threats blocked - number of threats that have been blocked by the Secure Browsing
component.
Help & Support
Use this view to learn more about your AVG 2012 LinkScanner for Mac.
Click the Open LinkScanner help link to open built-in help, containing basic info about the
application and its functionality.
Click the Visit LinkScanner forum link to visit AVG forums - a great place to discuss your issues
with other AVG users, customer support specialists and developers.
Finally, in case you encounter a really serious technical trouble, you can contact AVG directly.
Click the Send data button to send us a message describing the problem together with necessary
diagnostic information (collected automatically).
A V G 2 0 1 2 L inkSc anner for M ac © 2 0 1 1 C opyright A V G T ec hnologies C Z, s .r.o. A ll rights res erved.
15
Be assured that no personal or other sensitive data will be collected during the process. Sending
diagnostic information is also quite undemanding and won't affect your computer's performance.
4.2. Icon in the Menu Bar
The AVG icon can be optionally displayed in the right part of the menu bar. If it is not visible, you
can display it by turning on the Show AVG icon in the menu bar option in General tab of AVG
2012 LinkScanner for Mac Settings. Upon clicking the icon, you get a context menu resuming neatly
relevant options of the application menus:
Show/Hide AVG LinkScanner - click to show / hide the docked AVG icon.
Check for Update - click to immediately start the update process.
Open LinkScanner Settings... - displays the General tab of setting options dialog.
About LinkScanner Agent - shows the version of LinkScanner Agent.
Apart from quick access to frequently used items, the icon also indicates AVG protection status
(correct, warning or error).

16
4.3. Menu in the Menu Bar
Whenever the Main User Interface is opened, the AVG 2012 LinkScanner for Mac menu appears in
the right part of the menu bar:
This menu provides you access to a few basic options:
About AVG LinkScanner - displays a small dialog with copyright and version number
information.
More Information... - starts your browser and opens the LinkScanner for Mac site.
Preferences... - displays the General tab of setting options dialog.
Hide AVG LinkScanner - minimizes the Main User Interface (without turning the AVG protection
off).
Quit AVG LinkScanner - turns AVG protection off.
4.4. AVG Protection Status
The protection status is intended to show you, whether you are fully protected or not. When your
AVG 2012 LinkScanner for Mac is up-to-date and working, the protection status is correct.
However, when a non-critical part of the AVG protection is switched off or inactive, you are
immediately warned about the warning protection status. Finally, when a component is switched
off, or your protection is outdated, the error status appears.
The warning status may also mean that error status of some component is being intentionally
ignored. You can set this in the Ignore faulty states section in General settings.
A V G 2 0 1 2 L inkSc anner for M ac © 2 0 1 1 C opyright A V G T ec hnologies C Z, s .r.o. A ll rights res erved.
17
AVG 2012 LinkScanner for Mac uses several graphical indicators allowing you to view the
protection status of this application. The following screenshots show the docked AVG icon displayed
either normally (indicating correct or warning status), or with an orange exclamation mark (error
status):
You can also recognize the status by looking at the icon in the menu bar, when
means correct
or warning status and
means error. If the AVG icon in the menu bar is not visible, you can
display it by turning on the Show AVG icon in the menu bar option in General settings.
Finally, you can see your protection status in the left part of Main User Interface. The first
screenshot shows the Main User Interface in correct status, the second illustrates a warning status
(in this case, the Secure Search component is disabled), while the third one shows the warning
status with the Secure Search component inactive. Note that your Main User Interface always gives
you details about the error, even suggesting how to fix it.

5. AVG LinkScanner in your web browser
Your AVG 2012 LinkScanner for Mac functions within your web browser without affecting its
performance. It uses a set of informative icons to either show you the threat level of every search
result in most commonly used web search engines (the Secure Search component), or to warn you
in case a webpage you try to access appears to suspicious (the Secure Browsing component). The
set of icons (identical for both components) is listed in the table below:
The page has been successfully scanned and is safe. Please note that this
icon is not displayed on the Yahoo! server!
The page does not contain threats but is somewhat suspicious (questionable in
origin or motive, therefore not recommended for e-shopping etc.).
The page can be either safe itself, but containing further links to positively
dangerous pages; or it can be suspicious in code, though not directly employing
any threats at the moment.
The linked page contains active threats. We do not recommend visiting this
page, or forwarding the URL via e-mail!
The page can not be scanned (which can mean that is doesn't exist anymore, or
it is temporarily unavailable.
5.1. Secure Search
When searching Internet with the AVG Secure Search on, all search results returned from the most
popular search engines (Google, Yahoo and Bing - former MSN) are evaluated for dangerous or
suspicious links. By checking these links and marking the bad links, the AVG 2012 LinkScanner
for Mac warns you before you click on dangerous or suspicious links, so you can ensure you only
go to safe websites.
While a link is being evaluated on the search results page, you will see a graphic sign next to the
link informing that the link verification is in progress. When the evaluation is complete, the
respective informative icon will be displayed. Hovering over an individual icon will display brief pop-up
dialog describing the particular link in question.
Please note that the search results are generated based on a blacklist (database of known
malicious websites) and the evaluation itself cannot be configured!

19
Various pop-up dialogs are listed below:
There are a few settings for this component that you can adjust. The easiest way to access the
Secure Search settings dialog is by clicking the Configure link next to this component's name in
Main User Interface.
Please note that while in Mozilla Firefox browsers the AVG Secure Search feature is active and
running immediately after AVG 2012 LinkScanner for Mac installation, for Safari browsers it is first
necessary to install the appropriate extension. To do so, open the Secure Search settings dialog (by
clicking the Configure link next to this component's name in Main User Interface) and click the
Install button in its bottom part. Afterwards your Safari browser starts; all you have to do now is to
confirm your choice in the following dialog:
5.2. Secure Browsing
Present-day internet is quite a dangerous place to surf - exploited web pages might infect your
computer simply by visiting the affected site. The AVG Secure Browsing aims to prevent that. This
powerful feature provides you a real-time protection from the most serious online threats: malicious,
exploitive, and phishing websites. If enabled, it automatically scans the source code of any website
you try to access (either by clicking a link or typing in a URL) and verifies the webpage origin. If it
discovers anything suspicious, it will interrupt loading the website, and display a notification with
more details.
A V G 2 0 1 2 L inkSc anner for M ac © 2 0 1 1 C opyright A V G T ec hnologies C Z, s .r.o. A ll rights res erved.
20
The notification dialogs (listed above) use the same set of informative icons as the Secure Search
and are informative only. They serve just to notify you that the threat has been found and blocked, so
the loading of the page has been interrupted. Access to a potentially dangerous website itself is not
blocked; the decision whether to visit the page is completely up to you. However, the page shown in
the browser after closing the notification dialog will be just a fragment of the original one - it will be
displayed only from the start to the point where the threat was discovered and blocked.
There is no simple way to access the original infected page. However, if you have any reason to visit
the untouched original page (possibly containing an infection), you can disable AVG Secure
Browsing in the Secure Browsing tab of AVG 2012 LinkScanner for Mac Settings (which requires
administrator password since it disables the protection of the machine) and then reload the page (a
cache cleaning might be needed depending on application requesting the page because of
application internal caching).

6. AVG LinkScanner Settings
This dialog allows you to modify all adjustable settings of your AVG 2012 LinkScanner for Mac. It
is divided into several tabs - the General tab contains some universal settings, while Secure Shield,
Secure Browsing and Update tabs offer settings for respective components. The dialog is accessible
in three ways:
click the docked AVG icon to open the Main User Interface, then click the Configure link next
to any component's name. Note that the AVG 2012 LinkScanner for Mac Settings dialog will
then be opened on the tab related to the chosen component.

LinkScanner for Mac Settings dialog will be opened on the General tab.

General tab.
Setting options of major importance are protected by authentication, and are by default locked
(grayed out and inactive). To modify the settings you have to be click the padlock icon in the lower
right corner of every dialog:
Immediately a new dialog appears, in which you are prompted to enter administrator login name and
password. If you don't know the name/password, you will have to ask the person who administers
your computer:

padlock icon is now unlocked and looks like this:
If you wish to prevent further settings modifications, simply click the icon and enter administrator
login name and password once again.

6.1. General tab
This dialog allows you to configure basic AVG 2012 LinkScanner for Mac settings. There are three
sections sections in this dialog with specific adjustable items in them:
General settings:
Start AVG LinkScanner upon login - if the box is checked, the AVG 2012 LinkScanner for
Mac will launch automatically after computer startup, when a user logs in, or whenever the
application quits (e.g. if another application forces AVG 2012 LinkScanner for Mac shutdown, it
will be re-launched immediately).

Notifications:
Notifications are little pop-up windows that appear for a few seconds only, and inform you of less
important events than alerts. Check the box at the respective notification option you want to activate:
Show error status notifications - if the box is checked, a notification window will appear
whenever a component changes its status from correct to warning/error. Please note that if you
choose to ignore a component's status, the change status notifications for that component will not
be displayed. To learn more about AVG protection statuses click here. Ignoring error statuses is
described in the end of this chapter.
Show Secure Browsing notifications - if the box is checked, you will get a notification
whenever the Secure Browsing component detects a suspicious webpage or other kind of
suspicious connection, and the detected threat is NOT blocked. (In the Secure Browsing settings,
you can set AVG LinkScanner not to block threats of lower severity.) For threats of severity
defined to be blocked, the connection is always interrupted, and an alert window is displayed until
you decide to close it. For unblocked threats, only the notification is displayed, so that you are at
least informed that the webpage is somewhat questionable and that you should proceed with
caution.
Notify me upon scheduled update start - if the box is checked, a notification window will be
displayed at each scheduled AVG LinkScanner update, informing you of the update progress.
Click here to learn more about updates and their types.
Show notifications about major update/upgrade - if the box is checked, a notification window
will be displayed whenever there is an important update, or upgrade to a new version of AVG
LinkScanner available.
If the respective setting option is not applicable at the moment, because the related feature or
component is switched off, a warning icon
will be displayed next to its name. If you move your
mouse over the warning icon, a pop-up message will appear, explaining briefly why that notification
is not applicable now.

Ignore error statuses:
If a component shows error or warning status, and you decide to deliberately ignore it, you can
check the respective component here. This means that the AVG 2012 LinkScanner for Mac will no
longer report the error/warning status of the component, and won't display notifications about the
component status change.
No matter which section you're in, you can always change Position of LinkScanner notifications.
The white rectangle represents your screen. The tiny orange triangle shows where the notifications
appear right now (which is by default in the upper right corner). To change this simply move the
mouse cursor to any other corner and click. You will immediately see that the tiny orange triangle
has moved to selected corner - and from now on, the notifications are going to pop up here.
Finally, you can use the Reset button to set all AVG LinkScanner statistics (displayed in the
bottom part of the Main User Interface) back to zero.
6.2. Secure Search tab
This dialog allows you to configure some Secure Search component related settings.
Enable Secure Search - if the box is checked, AVG Secure Search is active and evaluating
safety of the results of the most popular online search engines. Uncheck the box to switch the
function off.

The following checkboxes allow to choose Internet browsers, in which you wish the search results to
be evaluated. This is being achieved by activation / deactivation of appropriate browser extensions:
Activate Safari extension - with this box checked, the search results will be evaluated in the
Safari web browser.
Activate Firefox extension - with this box checked, the search results will be evaluated in the
Mozilla Firefox web browser.
Creation date of DB files states last successful update of the database of malicious sites.
Please bear in mind that the AVG Secure Search feature is automatically active and running only in
Mozilla Firefox browsers. Therefore you may want to install a special extension to activate it for
Safari browsers as well. To do so, click the Install button. When your Safari browser starts, all you
have to do is to confirm (or cancel) your choice in the following dialog:
6.3. Secure Browsing tab
This dialog allows you to configure some Secure Browsing component related settings.
Enable Secure Browsing - if the box is checked, AVG Secure Browsing is active and, whenever
surfing the web, protecting you real-time from the most serious online threats: malicious,
exploitive, and phishing websites. Uncheck the box to switch the function off.
Block connections - whenever the Secure Browsing detects a threat on a webpage you are trying

to access, it will interrupt downloading the webpage contents so that the harmful code does not
get into your computer at all. You can specify the lowest level of threat severity to trigger the
interruption:
o Low will interrupt the connection upon detection of any threat. This option is recommended
and set by default.
o Medium will interrupt the connection upon detection of a threat of medium to high severity.
o High will interrupt the connection only upon detection of a high severity threat.
Please note that if you decide not to block low severity threats, then upon such threat detection, the
webpage will be displayed normally, only a notification pop-up window will be displayed so that you
know that the webpage is somewhat suspicious and potentially dangerous. Displaying the
notifications can be turned off in General tab, section Notifications; however, we strongly recommend
not to do this if you do not have a serious reason, because in that case you are not notified or
protected from the lower-danger webpages or connections in any way.
Additional Redirect Ports - any ports entered in this field will be redirected to the Local Port
above. By default, the port 80 is always included, too (not editable).
Finally, there are three button in the bottom part of this dialog. Clicking the Defaults button sets all
options in the dialog to the manufacturer pre-set and recommended values. Clicking the Revert
button sets all options in the dialog to the last user-saved values. Use the Apply button to save all
current changes to the settings.
6.4. Update tab
This dialog allows you to configure some Update related settings (managed by the Update Manager
component).
Click the Check Now button if you wish to update your AVG 2012 LinkScanner for Mac
immediately. This also called the manual update. The AVG 2012 LinkScanner for Mac will then
search online for new update files, and if available, download these and automatically update itself.
Under this button you can see the time of Last Successful Update. If the database had not been

updated lately, you will be informed by the AVG 2012 LinkScanner for Mac displaying error status.
Next, there is a checkbox called Run Daily Updates at. This box should remain checked to ensure
that AVG 2012 LinkScanner for Mac updates itself automatically at regular intervals, without your
intervention. By default, the AVG 2012 LinkScanner for Mac updates itself automatically at 5:00
PM. If you prefer a different hour, type it in the time box, or use the little up and down arrows to set
the hour.
If you (for any reason) have switched off automatic updates (by unchecking this box), do not forget to
update manually at reasonable intervals to stay protected. Click here to learn more about updates
and their importance.
Finally, you may use the Advanced button to access and edit existing web proxy server settings (if
you want to define a new web proxy, you will have to do so via System Preferences). Upon clicking
the Advanced button, the following dialog appears:
You can see the proxy server address and number of communication port (default is 3128) in the top
part of the dialog. The server may also require authentication. In this case you will need to fill in the
login details, too. These cannot be filled in for you, because each user account on the computer
might have different login details. Please mark the checkbox Proxy server requires authentication,
and type your proxy server username and password in the respective fields.

7. Updates
AVG 2012 LinkScanner for Mac contains a number of definition files with information on dangerous
or suspicious websites, and uses combined techniques to generate the final result (i.e. whether an
URL is dangerous or safe). AVG developers work hard to keep all these files and mechanisms up-todate, and any new definitions and improvements of these are delivered to you from AVG
Technologies servers via online update. Regular updating of your AVG 2012 LinkScanner for Mac
is therefore essential.
All update related settings can be adjusted in the Update tab of AVG 2012 LinkScanner for Mac
Settings dialog.
7.1. Update Types
Basically, there are two types of update in the AVG 2012 LinkScanner for Mac:
Manual update is an immediate AVG 2012 LinkScanner for Mac update that can be
performed any time the need arises. You can either open the Update tab of AVG 2012
LinkScanner for Mac Settings dialog and click the Check Now button, or you can click the
AVG icon in the Menu bar and select Check for Update from the context menu.
Scheduled update - within AVG 2012 LinkScanner for Mac it is also possible to pre-set
an update. The planned daily update is then performed periodically according to the setup
configuration. Whenever new update files are present on the specified location, they are
downloaded either directly from the Internet. When no newer updates are available, nothing
happens. The exact time of this automatic update can be set via the time box in the Update
tab of AVG 2012 LinkScanner for Mac Settings dialog. You can also use the checkbox to
turn the scheduled update off/on.
Please note that if the computer is turned off at the time of scheduled update, the update
will be missed without compensation. For this reason, we recommend setting up the daily
update time to an hour when your computer is most likely running.
7.2. Update Process
Whenever an update starts (no matter if it's manual or scheduled), AVG 2012 LinkScanner for Mac
will first verify whether there are new update files available. If so, AVG 2012 LinkScanner for Mac
starts their downloading and launches the update process itself. During the update process you will
get redirected to the Update interface where you can view the process progressing in its graphical
representation as well as its final result:

The first screenshot shows the situation when the process was successfully finished and your AVG
2012 LinkScanner for Mac was updated. The second one illustrates another outcome - when there
are no new update files available. Finally, the third one shows update failure. There might be a few
reasons for this, with limited or unavailable Internet connection being the most common.
From time to time, you may also encounter the following dialog:
This means that an important update, or upgrade to a new version of AVG LinkScanner is currently
available. Such updates usually take a bit more time to accomplish. You may start this update by
clicking the Continue button, or postpone it by clicking the Not Now button. If you don't want to be
notified about these important updates, open the Notification section in the General tab of your AVG
LinkScanner Settings and uncheck the Show notifications about major update/upgrade box. In
such case, important updates will be installed automatically, without any notice.

Please note that Firefox, Safari and System Preferences will be closed if running!
Please note that it is necessary to exit the AVG LinkScanner application in order to proceed with
the uninstallation!
8.2. Manual uninstallation
In most cases, you will not need to perform manual uninstallation. However, should the need arise,
you can remove all files related to the AVG product as follows:
1. Open AVG LinkScanner Settings and in General tab (General Settings section) uncheck the Start
AVG 2012 LinkScanner for Mac upon login item.
2. Quit the Firefox, Safari and System Preferences applications, if running.
