Comodo firewall’s defense+ keeps blocking my antivirus program when it attempts to update itself. It is blocking Avast 7.0, and I do not understand why. It was not doing this with version 6.0. Can someone help me understand how to stop this?

Sorry if I am in the wrong area, but I really need help and I would just like an answer.

Perhaps this may help: Comodo Firewall and Avast7
