Lanix X110 (Mexican made, generic android 4.4.2 OS) Random "ghost" apps appear from nowhere and other issues
Do this. Those are brought to you by some app integrated to system. If you could be kin enough you could realize that even advertisements appear on status bar and or drawn over other normal apps. But though even if you haven't seen ads in your phone, automatic installation only is too worse an issue to live with. 


Snatch Dr.Web antivirus from any source you're convenient with, 
Install it and then run a full system scan.
Take note of Adware originated apps, binaries, and frameworks if possible. The app reports Google Play Services also as an adware but don't delete it. 
Since you have kingroot, install a root file manager like Es File Explorer, or most preferably Solid Explorer and grant it root access. 
Navigate to the reported files and delete them except Google Play Services. 
Get back to kingroot and remove root access. Reboot your phone and you'll be good.


I did this on my Sony and all those things went away
