I've used Zone Alarm for years, in fact the same version 4.x. I trust it and like it.
On my nb I was using the default XP firewall, which was fine, but I missed the ability to control outgoing traffic. I've tried COMODO and like it. I had to work on it a bit to work with my home LAN but I was able to configure it to fit my needs. And with the support from the forums I found how to backup my configuration.
Over all I am a satisfied client. In fact I am considering replacing ZA on my other machines with it.
Nice job guys.
