Since there is no information, I would say that it's some sort of malware. Anything that Microsoft makes or HP, or Dell, etc. would have files online for people to look up. It may be some sort of spyware that changes names when it is deleted. Start up in Safe Mode and run AdAware, Spybot S&D. I would also suggest downloading Hijack This and posting your log in the security section. Somebody there will help.
