Unauthorized attempt to access system


Trying to use my phone, I`ve received a notification, a " prevention information" about an application that has been forced to stop for unauthorized attempt to access system in my device .
I said "ok, let`s push OK and see what will happen". So I push Ok button and find myself in app manager. No instruction about which application or what to do? I`ve ran an virus scan and clearing all the data in the browser and the notification message keeps coming .
Any help from you it will be useful :(
