Re: FREE antivirus
I like AVG and Avast the best. Avira Antivir is another good one but AVG and Avast seemed to do the best for me. I used them both together and didn't have any problems. Avast has IM protection and a bunch of other things and AVG has a good email scanner. I like the fact that AVG doesn't use really any of your resources and it does a good job at scanning but for realtime protection I would stick with Avast! but that's just my opinion.
Best of luck,
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.
