What's up with the supervision?

Yeah moin, I've been popping it up on my Huawei for a day now, as a banner and then it disappears again after 2 seconds…

That always pops up randomly.

Somehow that scares me…

Virendefinition and Avast are up-to-date and I have already run through 3 times completely, without result…

Does anyone have advice.

In which app are you there? Looks like a simple toast message, nothing is dangerous.
