Although my Desktop is Windows XP, my laptop is Freespire, a Linux system. It’s so hard to explain to most folk how Linux doesn’t have that many problems with virus’. The first thing a Windows user will say is, “Well Linux computers get virus too!” Most of the time without any knowledge of the “facts” they are spouting. But they are correct, it is possible for for Linux to get a virus… it’s just reaaaallly rare. However if you have Linux I would still get an antivirus of some sort… and if you have Windows, try a Linux live cd of some sort, Ubuntu or any number of the ever growing Linux herd of OS. Happy computing folks!
