My wallpaper has been replaced with "Warning: Spyware threat has been detected on your PC". I also cannot get to task manager. It says it has been disabled by the system administrator. When I go to regedit to enable it, as soon as I do it changes back to disabled. I have run superanti spyware and mallwarebytes and each time I do it cleans the viruses but then they come right back.

I am running window xp and need help getting rid of this stuff..
