Windows 10: False positive? Or something else?

I made the mistake of downloading something that had this virus, and I deleted the files within the folders that were affected by it originally It was a .Zip I extracted, if that matters and re-scanned my computer using Microsoft Defender Antivirus The default one and it said there were no new threats, yet it says on the "Virus & threat protection" screen under "Current threats" that "There may be threats on your device. After the scan is complete, you can review the threats found." And after I DO scan everything, it says there are 0 threats found? Is this a false positive? I also used

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.

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.
