2.3 Modules and Operating Mode. AVIRA ANTIVIR SERVER FOR WINDOWS, ANTIVIR SERVER UNIX

Self-Integrity Check

Each AntiVir executable binary is signed and performs a self-integrity check during startup.

The self-integrity check cannot protect against forgery (e.g. to check if the complete package is faked) or crafted attacks (e.g. the function call that performs the self-integrity check is bypassed). Such a verification has to be performed from outside the package.

Modules and Operating Mode

The Avira security software consists of the following program components:

• AntiVir Engine

• AntiVir Guard

• AntiVir Command Line Scanner

• Avira Updater

AntiVir Engine

AntiVir Engine essentially represents the scanning and repairing modules of Avira software. These are also used by the other AntiVir products.

AntiVir Guard

AntiVir Guard runs as a daemon process. It permanently monitors all user access in the network (on access) and it protects the files against viruses and unwanted programs. It immediately blocks access to infected files which can be automatically renamed, repaired or moved.

AntiVir Command Line Scanner

AntiVir CLS can always be launched from the command prompt (on-demand). Infected files and suspicious macros can be isolated, cleaned or deleted using a number of options.

It can be integrated and used within scripts.

Avira Updater

Avira Updater downloads current updates from the AntiVir web servers and installs them at regular intervals, manually or automatically. It can also send update notifications by email. You can update Avira AntiVir entirely or only the scanner.
