I should think that with all the crap that's online if you even have an internet connection, you need an anti virus program. My favorite is AVG Free. Easy to use, takes up little room and does not screw up most installations or other stuff the way Norton Antivirus and other programs often do. No fees for updates either, unless you need to buy the professional version. You can get it here: http://www.grisoft.com And thanks for the heads up, I'm scanning my system right now.
