I have been using Zone Alarm free for some time and have had no problems. All of a sudden my Firefox browser won't load pages, nor will Internet Explorer, nor will my IM software work. When I switch off Zone Alarm everything works well. My ISP suggests to uninstall then reinstall ZA. I did that but it made no difference. With the new installation there is a very short list of programmes and the ones I need, particularly Firefox, have the necessary permissions to work. Why does my ZA no longer work? I can think of no changes to my set-up which may have caused this.
Operating System:Windows XP Home Edition
Product Name:ZoneAlarm (Free)
