  1. Wacatac false positive


    Ok so i downloaded a simple vbs script that i created myself after i reset my pc. All it does is create a message box that can only be closed with task manager. Just today, i got a notification saying threats found and it said wacatac or something. How could a trojan enter through my own virus its a vbs file. I deleted it and defender didnt see anything

    :)

    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.

  3. defender false positive

    Hi Bob,

    To better assist you, kindly verify the following:

    • Where did you submit the file about Windows Defender being false positive?
    • Right after the recent Windows 10 update, your Zara Radio stopped working?
    • Regarding the 404 error, what application were you using when you got that error?

    Let us know.

    Questioning a false positive for a Windows Defender virus scan

    Anytime you suspect a possible
    false positive
    or you want a second opinion, submit it to one of the online services that analyzes suspicious files. There are also number of web resources (URL Link Scanners) which can be used to check suspicious/unfamiliar
    sites or get second opinions.
