6. AVG Components
6.1. Computer
The Computer component covers two main security services: AntiVirus and Anti-Rootkit:
AntiVirus consists of a scanning engine that guards all files, the system areas of the computer, and
removable media (flash disk etc.) and scans for known viruses. Any detected virus will be blocked
from taking any action, and will then be cleaned or quarantined in the Virus Vault. You do not even
notice the process, as this so called resident protection runs "in the background". AntiVirus also
uses heuristic scanning, where files are scanned for typical virus characteristics. This means that the
AntiVirus can detect a new, unknown virus, if the new virus contains some typical characteristics of
existing viruses. AVG AntiVirus 2013 is also able to analyze and detect executable applications or
DLL libraries that could be potentially unwanted within the system (various kinds of spyware, adware
etc.). Furthermore, AntiVirus scans your system registry for suspicious entries, temporary Internet
files, and allows you to treat all potentially harmful items in the same way as any other infection.
Anti-Rootkit is a specialized tool detecting and effectively removing dangerous rootkits, i.e.
programs and technologies that can camouflage the presence of malicious software on your
computer. A rootkit is designed to take fundamental control of a computer system, without
authorization by the system's owners and legitimate managers. Anti-Rootkit is able to detect rootkits
based on a predefined set of rules. If Anti-Rootkit finds a rootkit, it does not necessarily mean the
rootkit is infected. Sometimes, rootkits are used as drivers or they are a part of correct applications.
Dialog controls
To switch between both sections of the dialog, you can simply click anywhere in the respective service panel.
The panel then gets highlighted in a lighter shade of blue. In both sections of the dialog you can find the
following controls. Their functionality is the same whether they belong to one security service or another
(AntiVirus or Anti-Rootkit):
