    Microsoft Safety Scanner False positives?


    I routinely run MS Safety scanner on my win10 machine every weekend.Within 15 minutes of the scan it's reporting that its found between 10-15 files infected files, yet when I come back later after it's done, there are none to report and none have been removed???

    Microsoft Safety Scanner

    I have been using the Microsoft Safety Scanner for years. I always had the option to decide whether to remove a "threat" or not. However, my latest scan performed last night automatically removed all "threat" programs.

    What happened to the option to remove or not remove a threat?

    I prefer having the freedom to choose what to remove rather than letting a "false positive" be automatically removed from my computer.

    Microsoft Safety Scanner False positives?

    False positive for desktop shortcut scanner.lnk

    The 1.239.488.0 virus / spyware definition update that rolled out about 24 hours ago appears to be producing a false positive for any shortcut placed on the desktop called "Scanner.lnk". I can consistently replicate a false positive for Trojan:Win32/FakeSysdef
    with the following steps.

    • Create a shortcut to an exe file.
    • Place the shortcut on the desktop.
    • Name the shortcut "Scanner".
    • Run "Quick Scan".
    I don't get the same result by directly scanning the file, nor by uploading the file to www.virustotal.com, so it would appear this is as a result of a heuristic rather than a file content analysis. I also don't get the same result with a shortcut that links
    to a website.

    Can anyone else replicate? How can we go about getting the Windows Defender team to reconsider this heuristic? It's a bit heavy-handed.
