I have been using sygate personal firewall for a few years now and it run fine except sometime some files will get corrupted and have to use scandisk to fix the problem or reinstall the program. The interface is simple (my opinion) compared to ZA where you have to click here and there to access the correct function. So I can quickly configure Sygate. On the other note, I see almost all malware that will disable security application will surely disable ZA since it is so popular....
Thanks for the feedback Falcon21.

However, ZA’s interface is not that bad at all, configuration is easy like I said while ago (well, in my opinion as well).

About the popularity idea, I guess you have a point.

Yo!
