Alright. First off, I am using Comodo antivirus thats is free to the public.(which in my opinion, by far, better than avast, avg, Microsoft security essentials, nod eset 32, a lot of other antivirus programs out there. So I was wondering, Is there a way I can use only the firewall of any antivirus program? For example, the best firewall I've heard, and seen good reviews about is zone alarm. However, it is seen as a resource hog. I am currently using Malwarebytes pro with comodo. But Would it be a problem having 2 different firewalls running at the same time? Thanks And as previously mentioned above, I would Highly recommend, trying out Comodo antivirus.
