Creatures of the Wild, ...unless you really enjoy playing around with a program, tinkering, what ever, and are really computer savy. I can not say this enough do not down load as a new firewall or upgrade to Zone Alarm 5.0 through 5.1. It seems to be unstable and full of bugs and has reach a bloat point that has damaged a good firewall. Been loyal since July 2001 do not even remember what version was in use then? Hold to your old 4.5 version (like me) or get another firewall if you do not have one. I have been researching this since May. All these problems can not be newbies and/or over taxed systems causing problems. I still see what I believe are way to many people give it a try and then.... about the results. Wait for a more stable 5.xx or move on to the many good firewall solutions discussed in this forum. If I am wrong I welcome comments. I play nice and do not get offended. Plez do not get personally. Thanks.
