This is the app called Franco Kernel Manager, one of the best kernel managers that are out there… Even when it was outdated (which I think that’s the cause it got booted from the PlayStore?).
I used it to check the process of my phone and monitor the active and idle drain mostly, I paid for it a long time ago, but now it just fails to check the licence and it doesn’t let me use it fully… I think there must be a cracked APK over there…
EDIT:
Fortunately the app is back in the store and hopefully that update version comes soon enough!
Is your Ublock Origins & lists updated fully and configured right? Because Ublock Origins is supposed to be blocking the malvertisements from being shown at all.
At least it does for me on Firefox-nightly & Mull.
Yep, all up to date. UBO gives me the option to proceed (= show) the dodgy ads. Maybe something to do with my settings that it doesn’t block those outright. It’s a useful option for when I’m using cashback sites that I can temporarily grant tracking links.
