Comodo BoClean and Firewall

This is probably a stupid question, and I don’t even know where to post it, but what is the difference from a security viewpoint between BoClean and a firewall from any security company. It seems that BoClean stops bad stuff from coming in and getting established, but so does a firewall. Thanks. I have used BoClean for maybe four-five years. It is a super program.

BOClean does not STOP anything from coming into your computer.It intercepts Malware when it accesses memory and then stops it from doing it`s dastardly deed.
A firewall is a completely differant product.

Have a look here.
