10.7.4. Warnings Tab
The Warnings tab displays information on "suspected" objects (typically files)
detected during scanning. When detected by the Resident Shield, these files are
blocked from being accessed. Typical examples of this kind of findings are: hidden files,
cookies, suspicious registry keys, password protected documents or archives, etc.
Such files do not present any direct threat to your computer or security. Information
about these files is generally useful in case there is an adware or spyware detected on
your computer. If there are only Warnings detected by an AVG test, no action is
necessary.
This is a brief description of the most common examples of such objects:
· Hidden files - The hidden files are by default not visible in Windows, and some
viruses or other threats may try to avoid their detection by storing their files
with this attribute. If your AVG reports a hidden file which you suspect to be
malicious, you can move it to your AVG Virus Vault.
· Cookies - Cookies are plain-text files which are used by websites to store
user-specific information, which is later used for loading custom website
layout, pre-filling user name, etc.
· Suspicious registry keys - Some malware stores its information into Windows
registry, to ensure it is loaded on startup or to extend its effect on the
operating system.
10.7.5. Rootkits Tab
The Rootkits tab displays information on rootkits detected during scanning if you have
launched the Anti-Rootkit scan.
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 as well, 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.
The structure of this tab is basically the same as the Infections tab or the Spyware
tab.
10.7.6. Information Tab
The Information tab contains data on such "findings" that cannot be categorized as
infections, spyware, etc. They can neither be positively labeled as dangerous but they
are still worth your attention. AVG scan is able to detect files which may not be
infected, but are suspicious. These files are reported either as Warning, or as
Information.
