I am running Windows 7 with IE8 and ZoneAlarm Extreme Security version with Browser Security version I get frequent pop-ups saying, "ZoneAlarm Browser Security detected problem with stability of protected browswer. It will be restarted." It's getting annyoing. As soon as I click "OK", it pops up again. The browswer window functions normally.

What is causing all of these nuisance pop-ups, and how can I stop them?
