Avast 8x only works as administrator

Windows 7 Ultimate 64Bit e Avast 8.0.1483 130319-1, I’ve an avast registration.

I use my computer as a normal user without administration privileges, on my normal user account all avast shields are down with a red mark and sad face, with my administration account all seems to work just fine, when I switch back to my normal account all goes red again.

I did uninstall and reinstalled avast 3 times with the same results.
