Thanks again, nihil:

I checked out scareware and saw screenshots nearly identical to what I saw on my screen and am thus convinced that what happened to me was a scarewar attack, as you said. No harm done because I never opened their file. I deleted it. Ha ha.

Could not the Ad-Aware attacks come from an external source--some one firing virus bullets at my pc? I'm not certain I want to update Ad-A since the free version seems to be working as is. Also, would I want to add the Emsisoft product to Ad-A, or delete Ad-Aware first? I've heard that if you have too many anti-virus products on your system, viruses can find spaces between them to attack you. More is not always better?

Thanks for your continued support.
