Best AntiVirus (Free) From my this List?:?nortin

AOL Active Virus Shield *was* the best of that group, but unfortunately is no longer available.

The new McAfee could very well be *rated* the best, but based on past issues, it is bound to be a resource hog.

Of the remaining three, Avira is consistently rated the highest, although I personally find AVG to be more user friendly.

So in summary, the best product (McAfee) will probably slow down anyone with less than 2GB RAM. Between AVG and Avira it's a coin toss for a little better detection (Avira) or a little more user friendly (AVG).

Edit: I gave a 'thumbs down' to a "Top Contributor" above because they cited a source for test results and they weren't there. Your source should be/do what you say it is.
