Hello mac nuts. I am a fellow mac nut, been with the fam since appleIIc... but i've got to make a switch. the wrong one! architecture and 3d modeling kinda requires the purchase of a desktop pc... but i'm asking this question primarily for my girlfriend... for my pc has not yet arrived. her dell laptop has become increasily sluggish. i've seen many pc's bite the dust in this way in the past year due, it seems, to spyware, adware, and the like. how should she proceed to recover her computer? and how should i avoid the same fate in my pc when it arrives? (short of not hooking it up to the internet) thanks, r.
