zonealarm pro
Phoenix, I like you, was trialling the 'pro' version to, but got pi$$ed off at the dialogue box that pops up at startup. seemed that you had no firewall until you clicked the 'trial' item.
Totally daft and useless for me when I often startup the 'puta unattended to check emails.
So, I have canned the trial now, and just gone for the vanilla version. They lost a possible sale on me.
