Microsoft Defender Offline is an antimalware scanning tool that lets you boot and run a scan from a trusted environment. It utilizes Windows RE to run the offline scan.<\/p>\n

During the Microsoft Defender Offline scan, it may appear to the user that the scan stalled or crashed at 91%, 92%, or 93% on some systems. This article tells you how to check if the last Microsoft Defender Offline scan was completed correctly.<\/p>\n

Cause<\/h2>\n

The “Percent complete” indicator in the Microsoft Defender Offline scan is entirely inaccurate<\/strong>. For example, check these images.<\/p>\n

92622<\/strong> files have been scanned. The percentage is 93.<\/p>\n

95417<\/strong> files have been scanned. The percentage remains at 93.<\/p>\n

\"defender<\/p>\n

115417<\/strong> files have been scanned. The percentage remains at 93.<\/p>\n

As long as the number in the “Items scanned” increases, it means scanning progresses well.<\/p>\n

It’s OK if Microsoft Defender Offline closes and reboots the computer before the progress percentage reaches 100%. Not sure on what basis the “percent complete” value is calculated, but it’s not<\/strong> even approximate. Therefore, the field should be ignored<\/strong> completely.<\/p>\n

Check the status of the last Offline Scan<\/h2>\n

To correctly know the status or the return code of the previous Microsoft Defender Offline scan, inspect the msssWrapper.log<\/strong><\/code> file. The log file is located in the following path:<\/p>\n

C:\\Windows\\Microsoft Antimalware\\Support\\msssWrapper.log<\/pre>\n
The recent entries are at the bottom of the log. Open the log using Notepad and scroll to the bottom part of the file.<\/p>\n
If you see the following line at the end of the log, it means the last scan ran correctly.<\/p>\n
Offline scan completed with 0x00000000<\/pre>\n
(Code 0<\/code> or 0x00000000<\/code> means SUCCESS.)<\/p>\n
