Hey right now im Running ZoneAlarm that I like everywell. I heard that they are Special Firewalls that goes well with different Antivirus Software. So its this the best firewall that goes well with Avast 4.6 or there is a better Freewall Firewall that goes well with Avast!4.6?
I suggest a forum search as this topic has been covered a number of times.
Try Comodo Personal firewall it is free. I use it and like it very much. To donwload it click on the link.
