Dittos on thoughtomator's comments - if you are unsure what an archive is it's usually a .zip file or similar (e.g., .rar) containing other files (that have been compressed and stored). AVG and most other modern AV packages will scan inside these archive files since they are can be (and often are) hiding places for a virus.

Thank you for elaborating on this. Some people don't realize that asking implies almost total ignorance, and nothing can be assumed.

In a WindowsXP system, where might these files be located?

Unfortunately there are no absolutes with respect to file location, but some likely places (folders) are Program Files, Windows, My Documents or any other place you store/keep downloaded files from your e-mail or the Internet. The virus scan should identify the (archive) file name and its location and you should be able to navigate to the folder in question to examine/remove without having to hunt for it. The alternative is to search all of your hard disk (C:) for files with the extension .zip, .rar etc. then virus-scan the resulting list.
