AVG Antivirus Firewall Blocks Flock!

Hi Flockers!
Everytime I want to join a Flock session I need to turn off my AVG firewall. It’s no big deal, I still have Window’s internal firewall running, but it’s still mildly annoying… Is anyone else in the same situation? Have you found a way around it?
Thanks, flock on!
