    Possible False Positives, Wanting to Be Sure


    Hello Community,


    I have recently re-installed Windows 10 from scratch, using version 1809 as a Hyper-V role. One of the programs I install is Hyperoo which is used in a backup capacity for my Hyper-V instances.


    In doing this, I have been getting threats found like the following:


    Possible False Positives, Wanting to Be Sure 857682ef-d18d-48a5-86cc-f51913dea65f?upload=true.png


    These look pretty bad, but these are on transient files that soon disappear anyways.


    In the past 3 days I have gotten about 7 of these.


    I have had Windows 10 + Hyperoo installed for years and have never had this problem.


    I have also contacted Hyperoo and they say to disable the spool directory from Windows Defender locations.


    I have never had to do that, so I wanted to check here first to make sure that there isn't another consideration here that I am overlooking before doing so ... mainly making sure that my machine isn't actually infected somehow. Possible False Positives, Wanting to Be Sure :p


    I greatly appreciate any assistance you can lend here!

    :)

    Possible False Positive?

    Quite possible that it is a false positive. There are reports of WD Flagging as malware which in turn it is not.

    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.

    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.
