Save $20 on Zone Alarm Extreme Security 2010 from ZoneAlarm. 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. Advanced Access Protection New – specifically defeats new, advanced attacks that other firewalls miss like raw data access, timing, SCM and COM attacks. 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, blocking attacks that by-pass other defenses. Early Boot Protection – Uniquely protects your operating system during start-up before most security products have even loaded.
