I've been having this problem. The scenario is that I have Windows XP and for about a month now I've been getting this message that basically says: "You may have an illegal Windows program...blah, blah, blah" Then it asks if you want to solve this problem now or later. Of course I always respond later...but the other day either myself or my cat must have hit the response to solve now. Currently my desk top is black. I have all the icons and I'm able to do everything on the computer that I'd previously had done but I know that windows is not operating. WHAT DO I DO? SOMEONE PLEASE HELP ME!!!!!
