None. I run Linux (Lubuntu, specifically). Almost no one in the Linux world bothers to run virus checkers, and when they do it's because they are trying to fix a Windows machine and they have brought over the hard drive for that purpose.
Any time I have to get on my wife's Windows box to fix something, it is like torture. I don't see why people put up with it.
