Say i have a disc in the CD-ROM, say its Norton Anti-virus.. Then i take it out and put in a game called starcraft. The disc auto plays but instead of starting the game it starts anti virus. When i go to my computer and explore the CD-ROM drive, it shows all the files from the Norton anti-virus CD. In order to get the game to work i have to open and close the CD drive a bunch of times. Whats going on here??
