It is not a virus, it is a file that helps run your computer. I happen to be missing this file (that's how I found this forum), and it told me for several days that it could not find the file. NOw, it has locked me out of the computer. don't delete it, or you will have the same problem. a little hint, if your computer says it cannot find a file, immediatly replace it, and instead of shutting your computer down, put it on standby until you can fix it. Hope this helps!
PS It is in use by windows, so it will not show up in your process list.
