Firewall Apps
 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. |
 Comodo’s free Firewall is your first layer of defense against viruses, worms, Trojans, hackers and all Internet threats. Comodo’s Firewall uses Default Deny Protection to prevent threats from occurring, rather than just detecting them when it’s already too late. Whenever an unknown piece of software is introduced to your system, Comodo Firewall cross-references it with a white-list of over 15 million trusted files and applications. |
 Designed to harden and control the advanced firewall built into Windows, TinyWall includes a combination of features that sets it apart from both commercial and freeware firewalls. TinyWall does not display popups that “urge users to allow”. In fact, it will not notify you of any blocked action. Rather than displaying popups, TinyWall allows users to whitelist or unblock programs via various methods. |
 Windows Firewall is a software component of Microsoft Windows that provides firewalling and packet filtering functions. It was first included in Windows XP and Windows Server 2003. Prior to the release of Windows XP Service Pack 2 in 2004, it was known as Internet Connection Firewall. |
