Do I have a miner virus on my PC?

[k_2___]

OS: Windows 10 Home 64 bit
--------------------------------------------
A program quickly popped up for a split second then I heard my PC's fans speed up a little. I went to go check the task manager and where it says "CPU" the percentage appeared as 50% but then quickly dropped to 12%. I was literally just on YouTube with no other big programs.

It's really annoying me, I haven't installed any programs lately and the only thing I can think off that might have a virus is Photoshop CS6 I got. It might've been from GetIntoPC.com.

How do I remove a miner virus? Properly.

Run multiple AV scans, preferably from a bootable source.
Run multiple malware scans.

And I don't want to be the guy that says "I told you so", but this is what happens when you get software from a shady source. Especially if it is at an unrealistic price.

With all the free or valid low cost options, there is zero need for actual Photoshop, unless you know you need it, and the business case supports the expense.

I've done that, literally a CMD box just popped up for a split second again :/

Run the system in safe mode for a while. Does it still happen?
Look in the error logs to see if there is any weirdness.
