I installed the new ZoneAlarm Free at my Windows Vista Business X64 SP2 (with updates) and it crashes with a BSOD BAD_POOL_HEADER. I also run MS Security Essentials.

Do I need the mentioned MS patch KB979278 to fix this?

The computer crashes when I log into Steam. The computer is not crashing with PC Tools firewall instead of ZoneAlarm, but I like the functionality of ZA better. (if it runs stable of course)
