Comodo Firewall is one half of Comodo Internet Security which is what you are actually installing including the other half, the anti-virus component. You cannot opt out of installing this because it provides Defense+ (application monitoring) and Sandboxing. But you can opt of installing Geek Buddy (22 MB) by selecting the "Customize Installer" option.

Best Free Windows 64-bit Security and Privacy


Firewall, HIPS (Defense+)protection and sandboxing that match or better any other product free or otherwise; Excellent "memory firewall" feature, and it allows you to quickly switch between Defense+ security modes and configurations; Automatic updates; Installation can automatically configure your PC to use the Comodo SecureDNS (you can do this without Comodo Firewall).


CIS can be somewhat intrusive when first installed; No built-in help; Installs components you don't want; Uninstall sometimes leaves program remnants.
