Home page suddenly hijacked with ?Asus? battery display with adverts

[windbag]

My Tablet:
AsusMemoPad10 ME102A
Model K00F
Android 4.2.2

For the past few days, I keep getting a new display when I open the magnetic catch on my case (ie wake up tablet) - particularly if still connected to charge lead (intermittent if not)

It gives a full page of battery status & 3 charging options, with the lower half of the display is a series of changing adverts (see picture).
I've done nothing to request this, and I can't detect which app this is sourcing from, so I can't see how to stop it.

Doing anything makes the display scroll right and the go to my normal home page. I'm annoyed that something has hijacked my default home page as a billboard!

I have looked at the system->running apps, but there's nothing I can see that is obviously new.

Any ideas what it is/how to un-install or select an option to kill this?

Welcome to the forum

You have picked up some app related "adware" - a form of malware which is not likely to be that serious.
The malware thread linked in my signature, below, will cover this situation for you and give you good general advice.

All the best

Thanks for the speedy reply.
I'm not worried about it being truly malware, but whatever it is, it now qualifies as annoyance-ware!
I looked that link, and while all good stuff, I can't see how it helps.
I haven't installed anything in the past few weeks, so it seems that it's more likely to be down to an automated update - but of what?
If I could identify it, I'd just uninstall it - but that's likely to be a LONG job on a random selection approach.

How can I try narrow down the likely app source?
As I said, I tried system->running apps, but there's nothing I can see that is obviously new running all the time.

You didn't read it very well, then
Automatic updates are never a good idea in my opinion.

Post #6 covers adware specifically, links to Lookout and its information about their push add detection app, together with a link on the Play Store to download it. The recommended security app Cleanmaster also covers that area of protection within its range.

If you go to Playstore app and under My apps & Games you can see what was recently updated. It looks like a lock screen app. Do you use a custom lockscreen or launcher app? What are the 3 arrows on the bottom? Do you use a battery widget or optimizer?

For anyone who comes here with a similar problem/hijacked front page screen:
I managed to deduce it was an app called "Power Clean" (10 million downloads and 4.5 stars), which seemed to have been useful for getting rid of junk without being obtrusive up to that point. So I PM'd them via their Facebook page, and they admitted it was them and how to get to the settings to turn off the "facility". I told them it was very obtrusive, especially as there was no indication it was their app that was the source, and that their app was nearly uninstalled as a result.
They said "we get it" - but I've just had a go at them again as their next update over-wrote my setup and the "facility" re-appeared.
This time I've told them: "Congratulations, your updates are now blocked."

That's pure malware, simple as that. Purge, and if you have a g+ account so that you can provide a review, give them one star.
