Software: Free Antivirus Software (for one year)

If you're looking for just anti-virus software and not a complete 'security suite', then you might want to check out Computer Associates' eTrust EZ Antivirus software. Their now offering a one year trial version of it. If you want the two year subscription it only costs $19.95.

Here's the catch, this offer is for Microsoft Windows users, new customers only, and limited 1 per household.
