Is there any free version of eTrust?

Any recommendation?
How to set it to be just on-demmand and avast! the on-access?
I found (
http://www.my-etrust.com/microsoft/) but it's a free 12-month software subscription to CA's eTrust EZ Armor-LE Antivirus and Firewall security suite. Valid for new users only. Limit 1 per household. Not to be combined with any other offer. Customers may elect to upgrade to eTrust EZ Armor with enhanced firewall functionality.
Annual subscriptions can be renewed after first year at current renewal rate. Free software offer expires 2/1/05.
