My older P3 1.2 Ghz runs with 512 megs of 133 RAM. I have ZoneAlarmPro 6 installed and what is great about it is that it provides 100% stealth. I tested it and no ports were open at all. The thing is it is a memory hog and I have issues with it from freezing screens, to slowing down internet loading and surfing, to shutting it down in order to game (not online!); I have had it even interfer with offline Office Word work! (I've got to keep this PC protected without so much system resource being drained) From my extensive reading it seems many are having many of the same issues as myself. Another issue is my subscription is only days away from expiring. Can you suggest a really good firewall that has a small footprint, providing both inbound and outbound protection as well as stealth? I've looked at many, including Sunbelt's Kerio 4.xx, Bitdefender, etc., but I read conflicting reports of what is good and not good. To be honest I am totally out of my realm when it comes to this subject. The only firewall I've known over the years has been ZoneAlarmPro in its 4, 5, and 6 versions which means that it's interface/form of set-up is the only experience I have had with firewalls. So user friendly would be a real plus. Your help and suggestions will be most appreciated. Also, for my brand new s939 build, what would you suggest? Thanks.
