Windows 10: Potential False Positive?

Hello all, I've recently visited a website on Edge.Here is the websitehttps://www.unsightlyopinion.comAfter that, I do a quick scan, which resulted in a cache on Mircosoft Edge returning positive for Trojan:Script/Phonzy.B!ml.I then decided to also upload the file to VirusTotal before removing it.Here is the resulthttps://www.virustotal.com/gui/file/433c69a805f2ed0e636286a81e8e104cac3f3ae305a9109991b82098a961ce4a/detectionIs this really a virus or is it a false positive?I've removed the file since and the quick scans returned clean. I've also done a customized scan on the Edge's cache folder,

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.

 

Is this a false positive?

Hi, I am Dave, I will help you with this.

That is a false positive if only one AV on VirusTotal flagged that file, and your 4 safety scanner scans did not find any malware on your PC, then you have nothing to worry about and no further steps to perform.
