My first firewall was Kingsoft Net Shield, for which I even paid 50 yuan for a legitimate copy. But afterwards, it kept having problems and was not user-friendly at all. Someone recommended ZoneAlarm to me, and I found it to be simply amazing. So, I have been using it ever since version 4.5 up to the current version 7.0, and I plan to continue using it in the future. I also want to let more people know about this powerful firewall through this article and join the ranks of "ZA fans".
