Can’t stop the music! Went to a website that had music. Now, everytime I use the Vista sample video that I had when I went to the site, it plays the background sound it’s supposed to have, PLUS the music from that website!!! Restart did not help. A shutdown didn’t help. Virus checkers find nothing. It’s only when I use the SAME video I had when I went to the site. I did not download anything. What to do??
