just before while i was using WinDirStat to check my HardDrive usage, and while that was going, Norman (my anti-virus) came up with a message that it detected a trojan. It said, "Location: C:/Program Files/WinRAR/default.sfx" and the name of the trojan is "Vundo.gen29". after googling this, i found on Norman's page of recent Virus Definitions, that this was included. how of all things could WinRAR be infected? should i delete the apparent "trojan" or do you think it is a false positive?
