Free Anti-Virus Software...clever marketing ploy or useful software?
Ben Cordingley forwarded me a link where eTrust (CA) is giving away a free Anti-Virus and Firewall package, no doubt to capitalize on the SP2 release. Clever, but it's only free for a year as you'll have to update your subscription for presumably $50 in 12 months.
Regardless, it could be just the ticket for your Mom or family.
Another thought for Virus Protection while continuing to use the built-in firewall is GriSoft's AVG Free Edition.
