Windows Defender, "Potentially unwanted app found" gfdriver.sys

Windows Defender scan "Potentially unwanted app found" gfdriver.sys

I look in C:\Windows\System32\drivers\ and the file is nowhere to be found... Their description of this file is also empty except for calling it "App:NetFilterSDK"

https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=App:NetFilterSDK&ThreatID=268964

Anyone have any idea what this file may be or is this a bug in Defender?

Windows 10 Version 2004 Build 19041.329

All latest updates installed and even just ran DISM + sfc /scannow and it repaired corrupt files.

Solution 1:

Look in your Windows Defender Quarantine (Threats). It is probably there, and if so, then properly removed. It will go away after a few days so it may already be gone.
