Possible False positive?

Hello everyone.
I’m currently using the AMS here in my Android phone (5.1.1)
Today, after the scan it detected the app “Pixiv” as a malware. I think this is a false positive.

App link: https://play.google.com/store/apps/details?id=jp.pxv.android&hl=en

Is this really a FP or the “Pixiv” app is really a malware? it never got detected before my both Malwarebytes and Avast.

Thank you

And what malware name does avast give it?

It just says that “pixiv contains malware! It may harm your device”

I doesn’t say any other information.

Hello,
thank you for the notification. False positive was fixed.
