No anti-virus or anti-spyware product is 100% effective, so ZoneAlarm invented the OS Firewall. The OS Firewall monitors behaviors within your computer to spot and stop even the most sophisticated new attacks that bypass traditional anti-virus and security suites. New Advanced Access Protection - specifically defeats new, advanced attacks that other firewalls miss. 0-Hour Protection - prevents silent outbreaks from gaining system access even before the threat is known by other security programs. Program Control - restricts programs from malicious activities. Early Boot Protection -- Uniquely protects your operating system during start-up.
