^ partially right. What you got isnt technically a virus and I doubt any virus prog will do it. You got a adware pos. Google the name of the file and get info on removal that way. Tom Coyote forum is a good place to go for help.
If you simple delete the file it will come back because it has a hidden .dll somewhere else on the drive that is in windows system folder. It has a "run once" command that will keep reinstalling it on every restart.
The problem is that since it renames itself and it may have several files connected to it. Go to
