ZoneAlarm Pro Firewall automatically starts protecting you from malicious web content the moment it's installed on your machine using multiple tools. ZoneAlarm Free Antivirus is also available.
It will barricade your machine with immediate and total port blocking, then begin running in Stealth Mode to make your machine totally invisible on the internet - if you can't be seen, you can't be attacked.
ZoneAlarm Pro Firewall strives for simplicity without compromising your security. A 'getting started' tutorial explains controls and alerts to get you up and running quickly. And, to keep you confident that you're always protected, intuitive color-coded alerts rate security risks - in real-time.
