Windows 10: Microsoft Defender scan start event in event viewer - strange scan triger

Windows Defender Scans

According to the Event Viewer, a Windows Defender Scan is listed it as "Scan Type: Antimalware." Does that include all threats?

When I do a manual scan, and then go to see the results, the results aren't there and the Scan history usually only lists an automatic scan done at a previous time, and I have to go tot he event viewer to see it. Is there a tool that will allow me to easily view only scans?

Also, is a quick scan sufficient? What does a scan of the OS drive do that is different that the quick scan?

Windows defender ofline scan

Peter,

Event viewer maintains a record of the scan starting at

Application & service logs,

Microsoft,

Windows,

Windows defender,

Operational,

Event IDs 2030, 5007

• WDO failures that Windows knew about would be recorded as EventID 2031
  
• but WDO failures while Windows was not running would not be recorded.

But there is no record of its completion unless it finds malware detections to report in

Windows defender security centre,

Virus & threat protection,

Scan history.

• The Last scan entry in that dialog refers to Windows defender itself not WDO.
