Looks like you have a Bitcoin I have a few questions:
Did you download pirated programs?
Did you download Programs from untrusted sources? (Place that are not: Steam, Origin, Adobe etc..)
Did you have random shutdowns with your internet?

Secondly, run an offline Scanner: Go to windows defender > Virus & threat Protection > Advanced scan > Windows Defender Scanner offline > Scan now
Your computer should restart and offline scan, just let windows do his work.

I think you mean a bitcoin miner, and I don't think you can figure that out from what he said above. There are lots of things it could be (could be part of a botnet, could have some bloatware, etc).

@OP I'd wait for someone to come in here and read from FRST logs. If you're familiar with Farbar's Recovery Scan Tool, then go ahead and post your logs, if not then wait a little and somebody should come in and ask you for them (and show you how to).
