Nice suggestion, but not all Anti virus programs can detect all viruses on the gnutella network. Some AV's find & remove some, others find & remove others, and some find but cannot remove. There's 'other' options to AV's also such as anti-spyware programs, etc. It's interesting some of the AV programs that do work on the Gnutella network viruses are free whereas some of those that cannot remove or perhaps not even detect them are commercial AV programs.
