invalid notification

I have installed Avast mobile security recently. This month, I have regularly changed my SIM card (new operator Orange france instead SFR).
Since that, I recieve many times a day in my other mobile phone (the one of my wife) and by mail notification of the mobile position…I can check than the system is really efficient…
I CANT’T STOP that. The mobile ask me a pin code (I dont know witch one???)).

Any ideas?

I have solved the problem after a re-installation of Avast…everything is ok now (message new sim card validated)

Thanks!
