Avast Free Antivirus and Windows 7 Firewall - Updates don't work

Hi!

I have problems with Avast Free Antivirus and the Windows 7 Firewall that is set to block all outbound. (Whitelist-mode)
I’m using the latest Avast Free Antivirus (8.0.1489) on a Laptop with Windows 7 Professional 32 Bit.
I created a rule for the AvastSvc.exe for the webshield (and set “Scan traffic from well-known browser processes only” to not baypass the Windows 7 Firewall and deleted all but port 80 under troubleshooting-redirect settings-http ports.
→ Firefox can access http, but not https.
I found out that the webshield can not scan encrypted data and so I created a rule for Firefox, TCP 443.
→ Firefox can access https.
When I clicked on the Support-tab in the Avast User Interface no links were loaded.
I found out that its AvastUI.exe that is responsible for that so I created a rule for AvastUI.exe.
→ links in the UI work fine.
When I wanted to update the virus definitions, I got the message “Server not found”.
So I created a rule for ashUpd.exe.
→ Updates DO NOT work!!!

What rules do I need to add for the updates (and straming updates, cloud services etc.) to work fine?
