Windows 10: Potential false positive & can't find quarantined files

HelloI ran a full scan with Windows Security last night and it detected the following: Trojan:HTML/Phish.VS!MSRI can't provide a screenshot as I don't want to log in to my Microsoft account on the affected device just yet, as such please see the photo below:I quarantined the items but I can't see them in protection history. I would like to find them as I want to send them to my AV provider for analysis.I would also like to know if this could be a false positive? I ask this because I ran a full scan with Kaspersky Plus prior to the Windows Security scan and it didn't detect anything. I also use

Resolve Potential Defender False Positives - Trojan:Win32/Detplock

Windows Defender Security Center is pumping out notifications to suggest i have an issue but there are no current threats reported in the full scan so I'm thinking it's a potential false positive. If I remove all quarantined threats, they disappear but
start popping back minutes later.

Here's a screen grab from my PC:

I've reviewed all updates to ensure i'm on the latest patches, etc. and restarted a few time but to no avail.

Any ideas what's up?

 

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.
