Why am I receiving full-screen ads to install new apps?

[Android Central Question]

Since about Aug 16th I've been getting full-screen ads from AdSense wanting me to install an app. Sometimes it's a calendar app, sometimes it's the Mobile Performance Meter. Long-pressing the ad doesn't bring any sort of option menu. I can provide a screen grab if there is a way to do it in this forum.

Most likely adware from a app you installed. Boot into safe mode to verify.
