Potential problem when scanning a crashed computer

This is normal behavior by Microsoft Animalware software but not very well documented by the Microsoft Security Team.
 
If Microsoft Defender indicates no detections found at the end of it's scan and there are no items listed in quarantined upon completion, that typically means Defender completed it's scan and determined all scanned files were not malware related. If is not unusual for Defender (or any other security software) to suspect and warn about possible threats during a scan (a preliminary status indication) but later determine the file(s) were not an actual confirmed threat(s) upon completion.
 
I explain in more detail in Microsoft Security products indicates detected files during scan but does not show anything after completion (Post #22).
