I understand that. My question is why did I need to download Comodo in the first place? What's wrong with my Windows firewall?
Look, the easiest way is process of elimination. First off eliminate all the other security software you’ve mentioned that you or no one else seems to know if they even have a firewall that may or may not be conflicting. McAfee, Avast, Avira, Comodo? Whatever uninstall all of it.
As I said before you can leave Malwarebytes. Install MSE I’ve already posted the link. MSE will manage your Windows Firewall the one your having problems with. Doing this eliminates the possibility of any conflicts. And uninstall that dinosaur bug infested version of Comodo. I run Comodo, but not version 2 from ‘07.
If you still have issues after uninstalling everything and having only MSE (I say MSE for a reason because, it uses Windows Firewall), then we know it’s not a conflict in security software. And can try something else in the process of process of elimination.
I hope this helps,
Chris
Revising my post #80.
I agree with #79 and would go that route before considering installing additional programs.
