This is a virus -- this was the SAME VIRUS my brother infected my systems with a couple weeks ago. It was a thumb-drive virus. Disable your autoplays !!!!
Look for some piece of crap called "boot.com" as a hidden file anywhere on your computer, or in your registry. This is a pervasive little pest, hard to get rid of. It might have infected all of your external hard drives and thumb drives.
Google for it some more.

You have autoplays all over your system, it appears.
