Comodo technically includes an antvirus and a firewall, and the antivirus is quite good.
Comodo has many advanced features which can help protect your box if malware does become active on the system.
This includes the ability to lock down specific files and registry keys.
This makes it the best free firewall for computers which are older and sometimes struggle running firewall programs.
