The malware has permanently damaged the operating system. In this case, wipe and clean-install Windows. An effective disaster plan strategy for businesses is to create an image of a new working install, perfectly set up. Your case is an excellent example of when to apply that image to workstations. You can be up and running in a few minutes and only need to apply any updates that have occurred since the image was created. Since data should never be saved locally on workstations, data will not be lost. Malke -- MS-MVP Elephant Boy Computers - Don't Panic! FAQ - http://www.elephantboycomputers.com/#FAQ
