The Virut.O virus got past Nod32, infected it, thus disabling it, and was subsequently spread to many of the executables on my system. Has anyone else been hit with the virus, and found a way to clean it up, or is a re-install of Windows the only option? As a side note, in my 20+ years of experience with computers, this is the first virus I've encountered that has actually caused a serious problem. Up until the last year or so, I didn't even use AV software, and the only virus I've ever had in Windows was an email-spamming type, which is embarassing, but harmless. I use Nod32 now because I have family that share my computer, and they aren't techies. There is so much hysteria about computer security these days, with people running a half-dozen security programs because they think a virus might steal their children and burn their house down, this goes to show that even with a top-of-the-line security product like Nod32, you can still catch the rare virus that ends up being quite harmful. It's like getting hit by lightning I guess--extremely rare, but it happens, and no amount of protection is going to stop it.
