Avast is not recognized to the operative centre when Windows start

[IperJACK]

I've got an Avast Internet Security, license not expired. Windows 7 64 bit. PC Healt Advisor Pro.
When Windows start I see the small-white flag on the right zone of the toolbar.
When i click on it tell me :"Check antivirus Program"
Confused, I open Avast and I see the Options "additional protection" has only "Sites block" and "Auto sand box".
Avast is checked on programs that start at startup of Windows.
From the start of my license there wasn't any problem, After I install Es3t N0d and Zon3 Alarn. They all have got a license.
Why?
