The speed at which my internet home page of google has slowed down to a crawl, with either Internet Explorer or Firefor, and some pages that I click on after google loads, doesn't load at all. Either I have to click on it again and the page loads or it doesn't load at all. When I shut off ZONE ALARM, any of the pages load with no problem. I'm not an expert with Zone Alarm and would appreciate any help someone could give.

Operating System:Windows Vista Home Basic
Software Version:8.0
Product Name:ZoneAlarm Internet Security Suite
