High CPU usage

Hello,

I am getting a high CPU usage since I upgraded to macOS Monterey 12.1 (21C52).

I have a MacBook Air from early 2015.

When I boot up the MacBook Air, everything is fine, the CPU load is very low. I use it for some hours, everything is still fine. Then I put it in sleep mode (I just close the lid) and the next day when I open the lid, the MacBook Air gets hot, the fan starts to run and I see an abnormal high CPU usage without any process consuming the CPU (see the following screenshot).

I checked for viruses with Avira and it did not find anything.

I suspect an issue with macOS Monterey.

Any idea?

" I checked for viruses with Avira and it did not find anything."

There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX Foundation and Permission Limitation.

The The Built in Security is all that is required to protect the computer.

Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation.
