6. AVG Components
6.1. Anti-Virus
The Anti-Virus component is a cornerstone of your AVG Internet Security 2012 and it combines
several fundamental features of a security program:
Scanning Engine
Resident Protection
Anti-Spyware Protection
6.1.1. Scanning Engine
The scanning engine which is the base of the Anti-Virus component scans all files and file activity
(opening/closing files, etc.) for known viruses. Any detected virus will be blocked from taking any
action and will then be cleaned or quarantined in the Virus Vault.
The important feature of AVG Internet Security 2012 protection is that no known virus can run
on the computer!
Detection methods
Most antivirus software also uses heuristic scanning, where files are scanned for typical virus
characteristics, so-called viral signatures. This means that the antivirus scanner can detect a new,
unknown virus, if the new virus contains some typical characteristics of existing viruses. Anti-Virus
uses the following detection methods:
Scanning - searching for character strings that are characteristic of a given virus
Heuristic analysis - dynamic emulation of the scanned object’s instructions in a virtual
computer environment
Generic detection - detection of instructions characteristic of the given virus/group of viruses
Where just a single technology might fall short of detecting or identifying a virus, Anti-Virus
combines several technologies to ensure that your computer is protected from viruses. AVG
Internet Security 2012 is also able to analyze and detect executable applications or DLL libraries
that could be potentially unwanted within the system. We call such threats Potentially Unwanted
Programs (various kinds of spyware, adware etc.). Furthermore, AVG Internet Security 2012 scans
your system registry for suspicious entries, temporary Internet files, and tracking cookies, and
allows you to treat all potentially harmful items in the same way as any other infection.
AVG Internet Security 2012 provides non-stop protection for your computer!
