I have to warn you guys. I got the McAfee VScan 6.0 and have installed it on TWELVE Windows XP Systems (to try to duplicate) and on EVERY one, it errors on install (says not compatible with XP), and the updater crashes CONTINUOUSLY. Uninstalled and put on Norton and Voila - It worked like a champ. I have 3 of the McAfee, and even at Free it is a horrible product. Just FYI... Apparently even with a name brand you get what you pay for!
