So I suspect I have some kind of Malware or adware / Virus or however the defenition is on my phone. It have happened before, and back then I could isolate what the program was called and were able to delete it. Back then I traced the adware/malware (sorry I dont really know the difference) back to an app I got from Play-market. This time I suspect it came from an audio-recording app I downloaded in a hurry when I needed to record something for an assignment, and I delteted in straight after. A few days later an ad showed up from nowhere while playing Pokemon Go. Next time while I was in the dashboard. Anothertime while reading the news. I have a payed subscription of F-secure on my phone, but it doesn't find anything. I allso tried Norton Mobile Security with no resault. Last time this happened I was able to go through app the apps in settings, I googled on things that sounded suspicious untill I found what was not supposed to be there. But now I have Android 7.0 and only main applications are visible when I chose "all" I can not see any of the subordinate apps. I wellcome suggestions how to solve this problem. By the way, during this time I have a suspision that the phone is making "ghost calls" It has happened 2 times and I can not be sure that I didn't do them by accident. But sense I never ever make phonecalls by accident, and suddenly it has happened 2 times while I suspect harmfull code in my phone - they may be related.
