I have begun getting a strange update message on my Turbo. It is ostensibly from Amazon and asks me to update. When I try to do so, It says it cannot update because I do not allow third-party apps that are not on the Google Play store. Plus when I look at any of my Amazon apps (the regular app and the music app is all I have), they say they are already updated. Any idea what's triggering this "update"? This started on Thursday, after getting a message Wednesday from a www.[something]view.com that said I had a virus. I didn't touch it; just rebooted the phone.
