Query: AWFUL TERRIBLE WORTHLESS DANGEROUS!!!

DO NOT USE THIS PRODUCT!!! Foolishly, I didn't listen to the other reviewers on this site. Nothing but problems. The first thing ZoneAlarm did to my computer when I tried to install it was give me the Blue Screen of Death and crash my notebook computer. I rebooted and ZoneAlarm crashed it again. So I rebooted in Safe Mode, uninstalled ZoneAlarm, deleted the folder, and rebooted again. Problem solved. Then I snapped the disk in half. I wasn't even going to ask for a refund or try any of the workarounds - downloading updates, installing in safe mode, etcetera. I'll just buy something else. If I could give this product -negative five stars, I would. This is a terrible, awful, dangerous software product. Maybe they'll fix the problem in a later version, but right now ZoneAlarm is not ready for Vista. DO NOT USE THIS PRODUCT!!! STAY AWAY!!! I hope this review helps you.
