Windows 10: Why does Microsoft Safety Scanner detect 4 infected files during scan, but at the end of...

I ran the Microsoft Safety Scanner, and it found 4 infected files which it did not mention at the end of the scan. I ran it again partially until it found one infected file and then I cancelled the scan. I also ran the Microsoft Defender antivirus with full and offline scans, but neither scan mode found anything. Am I registering false positives?

Microsoft safety Scanner detects 13 infected files during scan, and the scan result at the end shows scan completed successfully without detections

Microsoft safety Scanner detects 13 infected files during scan, and when I get the scan result at the end it says "The scan completed successfully and no viruses, and other potentially unwanted software were detected".

Why does this happen? I have tried booting in to safe mode where it gets the same detections, and the same end result. Almost as the malware have found a way to cheat the Microsoft Safety Scanner.

 

Microsoft safety scanner finds no virus?

Hello Anxious,

I am Jaspreet Singh.

Microsoft Scanner works in steps.

So at first stage it will detect what may be an infected file and it will add that to a list. This is the number you see when you see the scanner progressing. These are not actual infections, just suspicious files.

Once the scan is done the safety scanner will match the suspected files with the most recent database of threats and then tell you the actual infections on your system. If the last number is 0 it means no actual infection was found.

 

Microsoft safety scanner 1.355.787.0 infected files

Hi eric, it's quite common for Microsoft Safety Scanner to flag some files during the scan, but upon further inspection of the files in the cloud, the end result is no detections.
