text: you need to completely wipe the hard drive and reinstall Microsoft (i'm assuming thats what you have) after installing windows. install McAfee or Norton (although I found McAfee to be a lot better protection) I would also install a pop up blocker (I use Ad ware and Spybot, they work really well) then continue installing windows updates then everything else onto your computer.\ndon't plug into the net unless you have to, until after you've installed McAfee.
