I'm using avast 8.0.1496 on Windows 8.1. I have my Windows firewall's outbound policy set to deny all connections (except for apps I allow through). The avast update is failing. Which exe do I need to add to allow avast to update? There are a dozen or so exe's in the avast install directory. I added AvastUI.exe, AvastEmUpdate.exe, and ashUpd.exe, but it's still failing. It definitely has something to do with the fw, because when I disable it, it updates fine.
