My dad's computer recently got infected with... something, to the point that the computer will load, but everything is frozen. I can only open task manager. The first sign of his problem was when his desktop was changed to blue with a box that read "This computer has been infected with spyware." I looked around the forum for solutions and found some about turning off web backgrounds, but the computer is completely frozen. Even in safe mode I cannot get any anti-virus or spyware programs to run. I was able to install hijack this in safe mode and run it using task manager while normally logged in. Any help at all would be appreciated. My dad is moments away from reformatting.
