This is how I've configured Comodo
Firewall Security Level >> Custom Policy Mode
Defense + Security Level >> Safe Mode
Never had trouble with these settings
In addition have Eset Smart Security with MBAM as On-demand scanner
I'm a little paranoid :;-D: and always like multiple layers of protection from malware
I use avast! IS,it have firewall.
