Thanks a lot for the help and that was exactly what was wrong. I thought that this option was an "if, then" kind of thing. Like if there is a disk left in the drive, then scan for viruses, but when there wasn't a disk complete shutdown. I guess that is what I get for thinking. (As we used to say...I thought like Lit, and got burnt.) Ha, ha, ha.
Thanks A Lot for the heads up and the help.
I Love Avast....now I will try to take the time to learn at least one thing new everyday.
