A pretty good deal I guess for anyone using Zonealarm firewall.

Here's the link.

Tip: when you first install ZA pro, it will say "the trial will be over in *** days".

Solution: ZA will email you the license key in a day or so. Cut and paste this KEY into the appropriate box in the "trial will be over" popup box. (just select, delete the sample key that's there and paste your new key)
