A really cheap friend of mine is still using dial-up. Running XP Pro. His machine pulled in SP2 months ago. Recently, it pulled in SP3, which I believe was corrupt. His internet will connect, but goes to a go.microsoft.com web address, but says page can't be displayed. His home page is set to yahoo. I managed to get rid of SP3, and computer properties says SP2 now. The install CD is SP1. I cannot get rid of SP2, because I cannot find it. I have been everywhere on the machine. Install CD says software is newer than CD, but SP2 is not on the list of installed programs. Can anyone help me find and dlete SP2? If I can uninstall, then I can start over with the operating system CD. I suspect a virus.
