Last night I tried Bitdefender AV scan online. I was impressed with three things.
I could monitor the scan process (much like spy-bot s&d)...instead of watching an animated graphic and waiting for the "full details".
A very simple, straightforward page without a lot of enticements.
When finished, the result was an object scan totaling 225,000+ and confirmation that no infections were present amongst them.
A Symantec scan required the same amount of time to reveal 25,000 or so files.
A Pandasoftware scan sifted through 60,000 files.
It'll require some more research for me to fully understand the subtle differences, but it seems worth mentioning. Routine periodic online scans supporting the resident AVG Free is my plan of action.

Oh, and 808chick...
I'm really impressed with your concise and inclusive signature lines. They create a rare glimpse of more precisely what "this is all about" than discussions alone can. Good Job!
