autosandbox exclusions don't stick

hi,
i am using avast free 7.0.1456 fully updated on win 7 home premium.

every time i start my computer avast warns me about my bluetooth program like shown in the attached pics. I am pretty sure this is a false positive so i “continue execution”. Avast places the program in the exclusion list but the same thing happens the next time i start the computer.

I think this started happening since the last program update. Any ideas how to stop the warning or make the exclusion stick?

The prgrams that avast complains about are intel bluetooth programs:
C:\Program Files (x86)\Intel\Bluetooth\BTPlayerCtrl.exe
C:\Program Files (x86)\Intel\Bluetooth\mediasrv.exe

thanks
