ZoneAlarm makes it easy. Unlike other personal firewalls, ZoneAlarm protects automatically from the moment it's installed - no programming required. ZoneAlarm barricades your PC with immediate and complete port blocking. And, then runs in Stealth Mode to make your PC invisible on the Internet - if you can't be seen, you can't be attacked..
