Re: virus scanner comparison site...Informative info
avira is good but the only thing I don't like is the annoying pop up that tells you to upgrade, it also has no email scanning. If you can live with those then I'd say go for it. I don't mind the lack of email scanning, I just hate the pop up screen. It is probably the best free AV as far as detection goes but I stick with AVG because all around I think it's a good package. It's all a matter of opinion, try a bunch of different ones and see which one you like best.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
