Personally I had not run a firewall on my machine for a long time. I have the windows firewall, the firewall on my dsl router, and the firewall on my wireless gateway. I realize that leaves a risk of malware communicating out. I've been putting a site together for family members & friends to recommend the best free software. I loaded Zone Alarm Free two weeks cause thats what I used way back in the day. I notice the free version prompts often. Now I work in the IT field so I can discern what to allow out and what not to, but I'd have to admit it can be confusing even to me. I can't recommend this to my mom, she would just get annoyed. I noticed they say in the non-free version they include a database of "known good programs" that cut way down on the prompts. Is there a free version that includes this database or is pay-for the only option for less prompts with an outbound blocking firewall?
