  • I deactivated realtime scanning on files through admin settings on my local sophos client. CPU usage went down immediately. Then I reactiveated it. Right now cpu usage seems to be normal.

    I don't know why this changed the behaviour. Before my cpu usage was high all day. Even reboots and Sophos updates didn't fix it.
