Avira was added?

Curious thing just happened. I opened Brave (it’s not the default brower, OS is win7 64bit, Brave Version 0.66.99 Chromium: 75.0.3770.100 Official Build 64-bit)
and there was a notification in the hamburger menu saying avira was added (and i think the option to remove or accept). I clicked on it to see it in the store and it’s this one:

That notification is gone because of that, so i couldn’t act on it (i know i should have just removed it), but then went into my extension and it’s not there, so i assume it was automatically removed?

Is there anything i should do? None of this appeared on chrome, FF or palemoon.
