No, you should not use both Comodo Firewall and Malwarebytes Antivirus simultaneously because they will conflict with each other. Both programs have built-in firewalls, and running two active firewalls at the same time will cause compatibility issues. It is best to use one firewall and its corresponding antivirus program, or to use an antivirus with a good firewall (like Malwarebytes) and disable any other firewalls, such as the built-in Windows Firewall.
