It appears to be a trojan horse that I picked up on Kazaa. It is in this location: C:\WINDOWS\system32 and I cant delete it. When I reboot, I see a quick flash of a dos window and then tiny firewall asks me if its ok to allow "explorer32" access to so and so at someplace. When i try to delete it says that it "can't be deleted because it is currently in use". A small bit of info on it can be found here.
