I think I have the CD I used to install Norton Internet Security. How do I boot to it?--you mean put it in the drive and hit "Run"?

A firewall CD won't help you. Borrow or buy an ANTIVIRUS CD (I recommend Symantec), and boot from it. It's designed to be bootable, and it starts a basic anti-virus system to scan your PC.

Most PCs have a BIOS setting that lets you use a CD as a boot device.

Okay, I did that, I think. It gave me an option of booting to the disk, which I selected, and then it said it was doing a scan. The scan only took 1 second--does it scan faster in that mode or something?--usually it takes an hour to scan my whole system. Anyway, it scanned and said it found no viruses, and now it's giving me the prompt for the "A" drive. Now what?

It's the 2003 version that has Norton Antivirus integrated with the firewall. It uses Symantec's antivirus updates. I think maybe the basic anti-virus system you mention is what it just did--is the "basic" part why it went quicker than my normal weekly scan?
