A few days ago, I noticed that my CPU is running high causing the fan to run almost constantly. I noticed in the taks manager and resource manager that dllhost.exe keeps popping up and then terminating, and WMIprvse.exe also runs sometimes holding onto 30% of the CPU for hours. I've also just had (while I was writing this) a blue-screen reboot (the first so far). With all the crypto-currency mining going on, I wonder if I've got something living in my PC.
I'm using the latest version of Windows 10, creators edition I think its called - I checked and applied all updates. For Anti-malware/virus my PC has Cylance and Microsoft Defender.
