Take it from me, who ruined TWO computers with a virus. Well actually it wasn't *really* my fault as I never downloaded anything/or went on any bad sites that I know of. My brother has had his Apple for 2 years now virus free. From my experience, DELLS ARE CRAP! I have one currently, and will never ever ever buy one again. Macs may be more expensive but in the long run they are better then these pieces of s***. I have a dell laptop that can't come off the desk, so there's no point in this laptop anymore.
