Just found a way to get Zone Alarms best package, including: firewall, anti spyware, and anti virus for free with updates for a year!
Firstly, follow the link and download the trial version of Security Suite. That gets you 14 days access.
When the trial is up, a button appears saying "get zone alarm free."
When you click it, it explains what you have to do.
Basically, you need to sign up for a "deal" to qualify for free zonealarm.
I signed up for a free trial to emusic, then got given a code (to activate zone alarm) which gives you 365 days of access to updates. Then simply cancel the emusic subscription before the billing date and everything is free!
Lovefilm was another free trial you could have used, but I have had one (or 6) in the past.
Its a very good security suite which is normally around $50, so to get it for nothing is a pretty good freebie I think
