im using win 7 firewall and i block all in/out connections.
tried adding ashUpd.exe, but no luck..

Allow all communications from Avastsvc.exe.

For UI online updates, allow AvastUI.exe.

You really need to allow all avast executables or many of the features/functions won't work correctly.
The major ones, AvastSvc.exe, avastui.exe, ashUpd.exe (Avast antivirus Updater), instup.exe (which I believe also deals with updates). Also AvastEmUpdate.exe the avast emergency updater.

You need to see that the OP has blocked all connections.

Well, that's certainly a bad idea.
@OP: If you want Avast to work properly, you need to allow it to connect.

You're welcome.

If you haven't included the avastui.exe executable as this does require internet access.
