Thank you both for your help. I am currently using Kerio 2.15 for my firewall. When the Avast update is paused I am still able to surf and do other things on the net.

When I open up my Kerio status screen I see the Avast Update accessing the internet, but then it just sits there and no data is being trasmitted or received. The Avast Update progress window goes through a few files checking to see if I have the latest version, then it pauses. It seems to pause on different files each time. Then 5 minutes later it continues and finishes the updating process like nothing ever happend.

(I just tried to update and it worked this time) Kerio told me that the local address was 2209, 2210, and 2211. I assume that is the port? It gives different numbers each time. Is there a way to make Avast use the same port numbers each time?

Thanks again for your help.
