I am trying to fix a friends PC running Windows XP Pro. When I click on his name at the Windows XP login screen, it looks like I am going to be logged in, then it says saving data and logs me out, taking me back to the original login screen. I suspect his PC was/is infected with the Sasser virus and had a lot of spyware on it. I tried booting into safe mode and had the same login problem. I tried the repair through Windows XP, and the same thing happened. I am stuck and need some help, anyone seen anything like this before?
