Windows 10: How d I report a False Positive to Microsoft?

I have Downloaded a file from Somebody I know


Windows Defender says it has a Trojan


Malwarebytes says it does not have a Trojan

None of the other people who downloaded the same file reports a Trojan from a verity of scans - NOD32, AVG, Bullguard

How do I report the False Positive to Microsoft?

JASC PaintShop Pro 8 - False Positive?

All of the tests on VirusTotal showed it as clear of this Trojan. The software manufacturer JASC has not existed for several years. I reported it as a false positive to Microsoft as advised. I have had no response from Microsoft. Will Microsoft be updating
Defender so that it this file is not listed as a 'severe threat'?

 

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.

 

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.
