Boot into safe mode with command prompt, and try executing things like Malwarebytes from there....as these new rootkit viruses seem to hook into windows Explorer, and the command prompt variant of safe mode appears not to let these processes execute immediately. Hence you need to be fairly savvy with your DOS commands (not too difficult for someone in the business with a memory), but as long as you stick to these instead of trying to use the windowed versions, you should be able to successfully initiate a MBAM scan. However, you'll need to update MBAM first though.
