Problem with advertising

[tifil24]

Hello,
 
I have a little problem of publicity. Let me explain.
Since last night, when I lock and unlock my phone, an advertising window appears. Only when I turn on to the Internet (either wifi or mobile data), when I have not Internet enabled, this does not occur.
When I click the multitasking button, there is no name in this window, I looked in the current process, I did not see anything strange. Nor even in the installed apps.
I tried various antiviral application to scan the phone, but nothing has been detected.
 
I have no idea what it may come, I installed an application store, but an ultra-known application, so it is not something sensible.
 
What do you advise me to do? (If it's possible, I don't want to do a factory reset ^^).
 
thank you in advance

In my apps list,  I have this:

I don't know what is it, and I can't uninstall it.

I found it !!!!!!!!!
I go to settings, security, device administrators, then I had something without any name like in the screen, and I disabled it.
Then, once I disabled it, I Could uninstall the app in the screen. And now I don't have no more this problem.

Thanks to all for your help guys !!! 🙂

I have the same issues with my new xz, it's twitter that serves ads, blatantly disrupting me when I use other apps, like signal from open whisper systems

Hi @Cyberpunk07, sorry to hear this.

I must say that I haven't heard of a case where the official Twitter app where the cause of something like this.  Do you get these as notifications or do they appear full screen?
