Uh… this is very interesting! The avast! software updater issue with IE10 is gone after manual updating my vps to 130618-3. I did a manual scan of avast! software updater and it reports software health: Good as mentioned from avast! software updater as follows:

Internet Explorer
Microsoft Corporation (up-to-date)
Local version: 10.0.9200.16611
New version: 10.0.9200.16576

My IE10 version is 10.0.9200.16618 and is up-to-date
