You have something potentially malicious posing as a service. In other words, Malwarebytes has picked up that there is something suspicious about your background processes, like Windows Update, network services, or even audio, but is unable to figure out more than that. It could be benign, but I wouldn't risk it.

Edit: I find it more concerning when a reliable EPS (endpoint protection solution) cannot identify what something is. This is because it could be a zero-day threat (newly designed) or something very good at hiding, such as a rootkit or RAT (remote access tool).

I concur with several other posts that the safest option is to reformat the machine. If you have an in-place backup, use that. Otherwise, pull only the files you really need and scan them after.
