Would like to report that I am having the same issue.
Running latest Avast with latest updates.
Disabling webshield, or enabling "Scan traffic from well known browser processes only" works.
A copy/paste from my Battlelog forum post about this issue:

I would like to report that adding *battlelog.battlefield.com/*, or any form of that. Has no effect on the issue, I cannot receive party invites and Battlelog doesn't not auto refresh. Only solution at the moment is either disable webshield, or enable "Scan known processes only".
