What is a rootkit?
A rootkit is a program designed to take fundamental control of a computer system, without
authorization by the system's owners and legitimate managers. Access to the hardware is rarely
required as a rootkit is intended to seize control of the operating system running on the hardware.
Typically, rootkits act to obscure their presence on the system through subversion or evasion of
standard operating system security mechanisms. Often they are also Trojans, thus fooling users
into believing they are safe to run on their systems. Techniques used to accomplish this can include
concealing running processes from monitoring programs, or hiding files or system data from the
operating system.
6.5.1. Anti-Rootkit Interface
The Anti-Rootkit dialog provides a brief description of the component's functionality, provides
information on the component's current status (Active), and also gives information on the last time
the Anti-Rootkit test was launched (Last rootkit search; the rootkit test is a default process running
within the Whole Computer Scan). The Anti-Rootkit dialog also provides the Tools/Advanced
Settings link. Use the link to get redirected to the environment for the advanced configuration of the
Anti-Rootkit component.

you have a real reason to do so, do not change the AVG configuration. Any changes to
settings should only be performed by an experienced user.
