Keep hackers and data thieves out of your computer with ZoneAlarm, the PC firewall that protects against Internet-borne threats like worms, Trojan horses, and spyware. ZoneAlarm provides the basic protection individuals need to secure their PC and keep their valuable information private.

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.

Includes a getting started tutorial which 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.

ZoneAlarm is free for individual and not-for-profit charitable entity use (excluding governmental entities and educational institutions).
