"Crashed after 4 days in my 64-bit system."
When it works: really good outbound protection, easy to use with good features for both novices and advanced users; extremely quiet (so much so, I checked it a couple of times early on to make sure my programs were getting through).
After 2 or 3 days of working fine, it started developing problems (i.e.:only letting partial downloads through) and by day 4 it crashed immediately after completing a download.Had to uninstall.
My system is W7 64 bit - is this thing 64 bit compatible ? That aside, this is a really nice firewall if compatible with your system, with nice features and an easy learning curve. I really hated to see it go, but have since switched to Comodo, which I consider to be the best 64 bit free firewall available, and has been working perfectly. If ZoneAlarm truly isn't 64-bit compatible, then CheckPoint should advise potential users of that. If it's just my system, then please accept my apologies.
