Galaxy S4 - App attempting to access system without authorization

[JT Peters]

I have been getting a message that an app attempted to access the system without authorization. The warning says deleting apps obtained from unauthorized sources may improve security. But I don't have any idea which app it might be. I guess I could try searching for each app on the play store until I find one that isn't there.

I do see Flash Player Settings in my list of apps. Probably got it from Adobe. I is not listed on google play.

Any other suggestions?
