Comodo Firewall FREE

Comodo Firewall is one of the most powerful and smartest personal firewalls you can ever see. It features both inbound and outbound packet filtering in combination with robust outbound application filtering at the network layer.

The new-look interface facilitates quick and easy access to all major settings, including the powerful and highly configurable security rules interface.

Comodo Firewall is your first layer of defense against viruses, worms, Trojans, hackers and all Internet threats. Firewall uses Default Deny Protection to prevent threats from occurring, rather than just detecting them when it’s already too late.

If the file asking for access is on the list, Comodo Firewall can be sure it’s safe for your computer to allow it to execute. If not, Comodo Firewall will alert you that a possibly malicious file is trying to enter your PC.

The software also boasts a powerful and vigilant packet filtering firewall. That helps you connect to the internet in a secure way while blocking hackers from making incoming connections.

Real time traffic monitoring enables you to react instantly to threats and identify bandwidth bottlenecks. It’s easy to use and features an attractive interface that lets even beginners change settings to their liking. Comodo Firewall comes with automatic updates for the latest in PC protection.

    I’ve been using ESS for many years, but then I changed to NOD32 (Antivirus only) + Comodo Firewall. To me, this is perfect combination.

    WARNING!!!!! If you already have this free firewall installed, updating it to this new version will WIPE OUT ALL YOUR SETTINGS, especially anything you have blocked. So write down all your blocked settings and, or, other important settings you currently have before you update to this new version. Man I have to say this upgrade pissed me the hell off by wiping out all of my program blocking settings and rules.

    The new COMODO version 5.8.213334.2131 now shows blocked intrusions in two parts, Firewall and Defense+ when you click on the "Summary" button. To get the intrusion summary, all you do is click on the intrusion number, for example 25 and it will give you the list.
