SteamUnlocked or just general piracy but but that I'm not aware of anything.

Doesn't Steamunlocked install a silent miner on your device?

I don't believe the actual one does but I do know there's a significant number of fakes around.

Personally I would go with the piracy option but that has its own inherent risks to anyone not familiar with what to look out for.

Ohww that's probably why, because of the fake ones.
