Note 3 Pro, Ads Popping Up And Poor Battery

[128MB]

I have a redmi note 3 pro from gearbest and trom the start i kept getting ads popping up when on WiFi by the TOOLS folder .. my battery life is also very poor, even after charging it drops to 60% within half an hour just sitting on my desk without wifi or any apps running.

wth is wrong with this thing ? And this app called KingRoot keeps popping up even when i did not install it.

Thanks !
