No product is 100% effective against viruses or spyware. ZoneAlarm's advanced firewall monitors behaviors within your computer to spot and stop even the most sophisticated new attacks that bypass traditional antivirus and security suites.

  • Zero-hour Protection prevents silent outbreaks from gaining system access - before other security programs can even detect the threat.
  • Application Control uniquely shields your operating system during start-up, before most security products have even loaded.
  • Early Boot Protection uniquely shields your operating system during start-up, before most security products have even loaded.
