recently after microsoft came out with the build 1511 update for windows 10 64 bit, my comodo firewall suddenly fails avast antivirus's compatibilty scan saying my firewall is a antivirus (when i install my firewall it gives me an option to install their antivirus but i always uncheck it).
right now i'm reinstalling windows 10 and i'm going to install avast antivirus and use windows firewall but i do want to use my regular firewall (comodo, since i'm not very comfortable with using windows firewall).
