Chances are that you inadvertently installed some adware along with an app or game. You may have to uninstall apps one by one until the issue goes away.

Either that or some ad-supported app (GO Weather Widget is KNOWN for this )

Yes try uninstalling the last application before the problem started. Also get something like cccleaner for Android and remove possible temporary files.
