Comodo Firewall & Windows Firewqall

Is it OK to have both Comodo Firewall and Windows Firewall running (Windows 7). Is there a performance hit with both on?

I’ve used both firewall enabled and will leave your connection a bit slower.

It is NOT recommended to have more than one software firewall running on Windows. I strongly suggest that you disable the Windows firewall if you are running any other firewall software. Failure to do this can cause slowdowns and/or random network access problems.

You shoudln’t run 2 firewalls or 2 AVs at the same time cause they can conflict. Comodo disables windows firewall for a reason. I would advise turning windows firewall off.
