Definitely an app that was previously installed doing this. As the other person said, go into your apps uninstalled and install the app that you didn't install.
It's definitely an app from my experience. You probably downloaded something without realising the app overlays over the screen. For me, it used to be a torrent app.
Go into Battery and Device Care > Battery > Click on graph > and then look at all the apps that are draining the battery. You might have to think about which apps that you recently installed and when the ads started popping up.
If you started getting pop-ups recently, look at your last installed app's which can be the cause of it. Uninstall then and check if the problem goes away
