I do bitcoin mining. Specifically, through https://www.nicehash.com/ I have been doing it for a few months. However i ran malwarebytes recently and found Trojan.Cryptonight and RiskWare.BitCoinMiner. I already know what the latter was and that it was under my permission. However, i am more interested in CryptoNight, as I have never seen it before, and I am concerned now. 

Is it dangerous? Is it linked to NiceHash? Or is it simply similar to RiskWare.BitCoinMiner where it is impossible for Malwarebytes to know if the program was unwanted?

Also, i do gaming. So i do not want mining to run in the background while i am gaming, only when i want it to.

Here is the scan results:

You have not removed it with Malware bytes and should.

This is a Trojan Horse that uses the infected computer’s resources to mine digital currency. Hence it uses your machine to do someone else's work.
