I have a generic android tablet running Android 4.4.2. There is an app that keeps reinstalling itself on my tablet called "settings" which is obviously not my real settings app. When it's installed I do get ads popping up occasionally. The icon ins a green triangle, (more like a baseball diamond), with a red exclamation point on the corner of it. I suspect this was on my tablet from the beginning, (it's a generic after all), so I doubt the usual methods will eliminate this. I need to be able to install unofficial apps anyway. Is anyone familiar with this malicious app?
