Your computer is not clean.
I created the same situation on a laptop that had w32/autorun.eh. I knew I was going to do a factory install anyway and had all the useful bits backed up along with an image mounted on a linux box. I ran several free tools including S&D on the infected system drive. 4 out of 5 tools left similarly buggered windows. The fifth tool failed to run at all. Further scans with the drive as a slave found several rootkits as well as more trojans
A moderator should be along in a bit to move you to the "am I infected" forum where an expert can help you.
In the meantime, assess your backup position, and make sure you have the proper boot/ reinstall/recovery media for your computer and be patient since the US holiday gives new users more time to ask for help and may make some members unavailable due to real world obligations.
Once you're clean, we may be able to figure out how to repair specific damage, but you need to be sure you're clean first.
