If you check those items under the PUP (Potentially Unwanted Program) heading, you can flag them for quarantine and removal.

Both have FusionCore.C in their file names. When you run the AdwCleaner executable (adwcleaner_8.3.1.exe), it finds the two offending PUA elements right away. That goes double, because while Defender flags FusionCore.C and other adware instances, it doesn’t offer its own clean-up capability (or even remediation advice). That said, cleanup tools like AdwCleaner can be helpful. Now that Microsoft Defender has shown itself to be a great first-line of security defense for Windows PCs, I don’t recommend third-party AV or other real-time protection tools anymore. Because AdwCleaner Roots Out PUAs, Use It! It’s free and doesn’t install so it inflicts no system footprint, either. It did, so I can report that AdwCleaner roots out PUAs. This morning I ran Malwarebytes’ AdwCleaner (v 8.3.1) to see if it would make it go away. It’s named FusionCore.C and it shows up as low-risk adware. You can see the Windows Security log trace entry for this item above. For months now, I’ve been seeing traces of a low-risk “potentially unwanted app” (PUA) on one of my Dev Channel test PCs.
