It started after last update

Most likely cause is that a 3rd party app that you installed is doing it.

Because you allowed it. Stop installing crappy apps and read every pop-up before agreeing.

What is adware?

The ultimate goal of many cybercriminals is to make money -- and for some, adware is just the way to do it. Adware does exactly what it says on the tin -- it's designed to maliciously push adverts onto the user, often in such a way that the only way to get rid of them is to click through to the advert. For the cybercriminals, each click brings about additional revenue.

In most cases, the malicious adverts aren't there to steal data from the victim or cause damage to the device, just sufficiently annoy the user into repeatedly clicking on pop-up windows. However, in the case of mobile devices, this can easily lead to extreme battery drain or render the device unusable due to the influx of pop-up windows taking up the whole screen.
