Some files cannot be opened for checking because they are being permanently used by the Windows operating system or some running application. It's not possible to infect them by a virus as well as to check them.

If a virus is found during an AVG Free Edition test and the status is Infected, Embedded it means that the virus file is part of an archive file (ZIP, RAR, CAB...) or part of a self-extractor archive (EXE). AVG Free Edition detects this file of course but is not able to remove this file automatically from an archive file and compress it again without this infected file or move it to the Virus Vault automatically because of data security.

During last years, there have been many computer viruses, especially "worm" type of viruses, which are distributed mainly via e-mail. This has caused a panic for users, which is parasiting a special group of messages called HOAX, which are NOT based on truth. These false-alarm messages are usually composed using the same scheme: Warning of some extremely dangerous, dramatically spreading virus and following a demand on some user action. In best case, they are asking the user to send this message to everyone in user's contact list (action is known from "chain" games), which causes the e-mail to collapse because of overload. In worse case, these messages ask to delete the suspicious virus, altough the file is actually a CORRECT system file. Deleting such files may lead to serious problems (some programs will not work, or the whole system may crash).

The strange manners of the Internet Explorer on your PC (automatic pop up of the web pages with a suspicious commercial content) or automatic redirection of your home page to the another one (as described - erotics, warez, etc.) may not be caused by the presence of the virus but the other malware also known as ADWARE or SPYWARE.

A Trojan Horse is a malicious application, which can not spread itself. Original Trojan Horses were programs which acted as a useful utility. Although, in fact, their start used to cause damage to disc content (or part of it).

Adware is not detected by AVG Free Edition as you know, because when you install different software, (for example DIVX5), you have to agree that this will install these types of applications and that you agree with what it does on your PC.
