I have Kapersky on several of the machines at work and at home, some at work are running Norton Anti-Virus, and the kid's computer at home has Panda. Used to run McAfee, but had problems that wouldn't go away, but partly due I think to some of the apps I run here. Kapersky is one of the best around, not easy to set up, but updates available usually 2 times a day.
