Welcome to Android Central! Does the ad show up when you're using the browser, or in the lockscreen? That's two different places.
If the ad shows up in your browser, it's likely related to the site you're visiting -- avoid that site. If it shows up on the lockscreen, then some app you installed came with adware. Uninstall apps one by one until it goes away.
