McAfee Scanner Service running high cpu with On Access policy not enabled

[Former Member]

I have a machine where the McAfee scanner service is running high CPU (around 98%) however its still the same when I change the Threat Provention policy for On Access scanning to a policy where its not enabled.

Has anyone else seen this type of behaviour on a device.

Probably an ODS running. Check the ODS log. 

in run line type %deflogdir%
look at OnDemandScan_Activity.log to confirm 

KB88205 covers some of this topic.

I have had a similar issue which Tech Support could not resolve.  At about 5:00 pm most days, McAfee Scanner Service started and CPU usage spiked to 90+%, rendering my computer basically unusable at the time of day when I have been trying to complete time-critical work.  McAfee UI did not indicate that a scan or update was running, and MVT did not detect any issues.  Today, a light bulb went off:  could Win10 have started something?  Sure enough, Task Scheduler in Win10 Control Panel has a task:  "DAD.Execute.Updates" triggered to start the program:  "C:\Program Files\Common Files\McAfee\DynamicAppDownloader\DADUpdater.exe" at 5:01 pm.  I reset the trigger to fire at 5:00 am.
