App identified as a security threat on Android

I own a Huawei phone and I have just received a notification (from the phone, not an app) that Prey was “infected and removal was advised”. Has anyone got the same message? This has not happened on my Pixel (yet).

Yes, the same happens on my daughter’s Huawei Mate 10, however, an older Huawei Honor 8 does not complain.
You can just ignore the warning and check the “Don’t remind me again” box.
