It seems strange to me that Comodo Internet Security currently uses the logo from Comodo Firewall Pro instead of its own logo. On the Comodo website CIS and CFP both have their own logos:

Maybe it’s because Comodo Firewall Pro is the established brand, but it just seems strange to me that CIS has its own logo but does not use it.
