i had zone alarm pro installed some time back and i just didn't like it. gave me problems. probably due to the fact that it wasn't legit. it wouldn't allow me to use irc and it would make my online gaming a complete disaster. so, now i'm useing zone alarm free version and EVERYTHING works great. besides the spyware blocker, antivirus and the other crap pro cumz with. what is the difference between zafree & zapro in means of their firewall protection?
