ZoneAlarm Free Firewall blocks viruses that antivirus alone misses, stops hackers attempting to break into your computer, and unlike the default Windows firewall, provides outbound firewall protection to stop spyware from phoning home and botnets from taking over your PC. ZoneAlarm Free Firewall is easy for anyone to use. It operates automatically, due to its powerful DefenseNet cloud service, so users are not interrupted with unnecessary alerts.
