Processor operates at maximum capacity regardless of task complexity
It seems like you're suspecting a malware infection given the high CPU usage. If you think it might be a virus, restoring Windows could be the fastest solution.
You’re definitely infected. Because you’re unsure of its extent, I’d disconnect all other storage devices. However, keep the main drive, perform a low-level format, reinstall Windows, and add Avast or Bitdefender (the latter may struggle with some current threats). Connect the drives one at a time, then let the antivirus scan and eliminate the malware. In the worst situation, you might have to erase every single drive.
It's not consistently happening, but the performance seems fine. I'm trying to figure out what kind of virus this might be, though I'm not very familiar with them. I just know it could be a keylogger.
It's referred to as a power virus. It gained significant attention during the late 1990s and early 2000s. https://en.wikipedia.org/wiki/Computer_virus
