ZoneAlarm is a good firewall... do not be discouraged with all the opinions and high sounding jargon that is being passed around. Was no need to purchase it though! The Free Version works just as well.
My experience goes back some 10 years and never once has there been any invasion of my system. Security is all about being careful, where you go and what you do. There is no miracle solution.
Hope this helps. All the best!
Ok, now that I've purchased Zone Alarm, I am hearing it isn't the best. Maybe I can bring this back. What do you recommend?
