Avast! Internet Security (NITRO Update) Auto update problem

[Be Secure]

Avast! Internet Security (NITRO Update)did not update the VPS automatically,i have to do it manually.

Steps taken in order to Automatic update start again:1.Repair option with multiple restart
                                                                                    2.Reinstall AIS
                                                                                    3.Reset all setting
                                                                                    4.Make sure that Streaming updates are ON(actively recived updates)

Result:failed.

BTW, i am not worried about it because i know VPS consolidate the streaming updates.just to inform Avast! team.
