I have a virus disguised as Realtek HD Audio.

Starts after about 15 minutes following reboot, uses 25% of CPU, and runs some sort of mining program on my GPU.

It is killed easily by ending the task. Not detected by Avast. I only saw it because ~/AppData/Local/Ethash was taking a lot of space (more than 5 GiB), and I don’t run Etherium mining things.

Seems the exact same as reported here: https://forum.avast.com/index.php?topic=188819.0

But that was over 120 days ago.
