Question CPU racing?

[robert600]

Win 10 home ... fully updated.

For the last month or so when i power up my laptop, within moments after booting ... the cpu goes to 100% and the fan kicks into high speed mode. In an effort to see what's going on, I open task manager. When I do, I see cpu usage at 100% but it then very quickly drops to 5% or whatever before i can see what process was running. Leaving task manager on and getting on with things ... CPU operates as expected but ... if I turn task manager off, the CPU starts racing again!

It's not a huge deal to leave Task manager running in the background but I would like to solve this if possible. Any suggestions?

malware scan the system?

Try running Process Explorer.

Alternatively open up PowerShell as an admin and run this command (from https://superuser.com/questions/176624/linux-top-command-for-windows-powershell)

While(1) {ps | sort -des cpu | select -f 15 | ft -a; sleep 1; cls}

This will list processes by CPU usage.

This behavior is similar to malware, specifically miners. They usually only check if you launch Task Manager to hide themselves.
