I have some solutions for you that may help to improve the situation and I ask you to perform this step while ensuring that you are safe:

• Double-click Windows Defender Scheduled Scan located in the center pane.
• Click on the Conditions tab, uncheck all the options and click OK.
• This will clear your scheduled scan. Double-click Windows Defender Scheduled Scan, select the Triggers tab, and then click New.
• Create a new scan schedule that suits your needs, choosing options that strike a balance between protection and system efficiency.
• As a guideline, we recommend scanning (at least) once a week so that you are unlikely to notice an increase in CPU usage.
