Watch this important tutorial to learn how to increase the firewall protection that comes with Windows. ZoneAlarm is a two-Way Firewall that makes your PC invisible to hackers and stops spyware from sending your data out to the Internet. ZoneAlarm replaces the default Windows firewall to provide true two way protection. Unlike the standard Windows firewall it does not assume that all outgoing traffic is harmless.
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.
