Stumbles across this site reports test results for various antivirus software. Sort of interesting.

I use Alwil avast! 4.0. Seems to have gotten a 100% rating.
How did your vendor do?
I am trying to find an alternative to the big behemoths (norton & mcafee). Avast is also free, so I can't complain. Also using mcafee's free online virus scanner as a backup.
I am discovering that with a little work, freeware products can do as well as retail products. Time for me the think outside-the-box more often.
