Does CIS include Comodo Antivirus and Comodo Firewall or not? Are they separate?

Are all these separate products that must be separately installed? Is there any package that includes all of them? Do I have to install 3 different products to get the full spectrum of defense? I ask this because I can not get this from the product information available at the front page.

Comodo internet security contains the AV, Defense+ (HIPS, Sandbox) and Firewall.
