constant ~10% cpu time

Avast Free Antivirus / Premium Security
1

Avast is causing WMI Provider Host (WmiPrvSE.exe) High CPU Usage, running around 10%.
Anyone have any ideas why?

I am running Windows 8.1.

Thanks,

    Have always used it (for years), as well as the other two.

This constant 10% cpu load probably started in the last few months.

If I look at the processes in the Task Manager, WMI Provider Host sits at about 10% CPU time. I remember that it used to be much lower when the computer was idle.
When I bring up the event viewer and look at Applications and Services Logs Microsoft > Windows > WMI-Activity Operational, select an error in the list, find it’s ClientProcessId,
then look it up in the Task Manager Processes tab, it points to avast! Antivirus.
