Need some advice around malware/viruses on android

Hello,

I've been looking around for an application that tracks application installs.
Especially for malware installs.

Let me explain the situation:
I've got a smartphone with installed apks (all legal from the playstore)
After a while I am trying to find out what problems are causing some random ad popups (about dating for those who are interested) it's caused by an apk called recents.
I always delete that program. But it seems that it reinstalls itself, every now and than.

also since today I've got an shortcut on my main screen that is called coobrowser (not coolbrowser although it has the same icon image, tried to find out where it came from but I can't find an apk either)

I know some applications:
os monitor is a good one though it doesn't accomplish my needs. (I can see the connections but there it stops)
Catlog doesn't make me any wiser

I hope someone know what I'm talking about and has this kind of application in reach.

TLDR: In need of an application install tracker that monitors which applications open a port for another application install (read malware)
