Windows 10: Why does Windows Defender not understand "False Positive"?

Almost daily now, I've had to clear a "threat" from Defender's "actions needed" list on a specific program that is a false positive.


How do I make it work as expected?

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.

 

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.

 

Windows Defender false positives

Hello,

Our company produces software protection solutions. One of our technologies protects *.exe and *.dll files by making the program code encryption (obfuscating). Such solutions are called "packers". The problem
is: Windows Defender on Windows 10 (embedded, home etc.) marks the protected software as a virus (Trojan). And of course there are no any maleware inside the application. So how is it possible to avoid false positives. We have already use IEEE software taggant
system but, as I see, it does not work with Windows Defender.
