Thanks for the help. It worked (the download scan). I decided to give the for-pay version of Avast! a trial, so I downloaded it, too, and installed it, and immediately set it up to do a scan of my three drives while I went to lunch. Worked fine. If it behaves for me, I’ll be delighted to pay for it.

I’m using the VISTA firewall at the moment. It seems to be working ok.

I’d been running the ZA internet suite beta for a couple months, but it really slowed down reboots and file executions, and crashed a lot (supposedly an advanced beta, too), so I just got tired of it.
