Ask Comodo not me. But please stop arguing. I proved my point and the screen shot validates it. Comodo has always offered there firewall as a separate download. Maybe the installers are all the same size encase you want to try CIS. That way there the installer is already in your pc. What is the big deal about 144MB? Do you only have a 1GB HDD? Any further questions please refer here.
