Windows 10: How can I know if Wacatac.B!ml is a false positive or it's a real positive?

So I scaned my pc and windows defender says that one program has the virus wacatac.B!mlthis happened when I downloaded a zip and unziped it. I readed that sometimes windows defender thinks that a .exe unziped has the virus, but the virus is in other program. Anyway I never executed that because I never needed to use it and I already deleted it, so how can I know if is a true or a false positive?*** Moved from Spanish Forum ***

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.
