After upgrading the ZoneAlarm Pro from version 7.0.337.000 to 7.0.408.000 vsmon.exe began to use 100% of CPU, so my notebook became unusable. Restarting doesn't help. I leaved the program for a few hours (in case that it has something to finish). The only result was the increasing of the CPU temperature up to 70 C. Shutting down the ZoneAlarm Pro was the only helpful solution. I don't think that the downgrade to v.7.0.337.000 is an option. Waiting for next version - too. Now I am without any firewall. How can I find what cause vsmon.exe to use such a CPU resources?
