On December 12 Zone Alarm Pro issued a critical update 3.5.169.002 which I promptly installed. I have had issues with Zone Alarm's VSMON crashing frequently and randomly every since. Each time this crash occurs all of my settings are wiped out including my password.

I have opened up a trouble ticket with Zone Alarm asking about possible resolutions of this issue and would recommend that you use caution in installing this update until Zone Labs issues a new update or fixes this issue if you do a lot of custom configuration.
