Hi
I looked in the error log:
Code Integrity determined that a process (\Device\HarddiskVolume3\Program Files (x86)\Microsoft\Edge\Application\msedge.exe) attempted to load \Device\HarddiskVolume3\Windows\System32\sysfer.dll that did not meet the Microsoft signing level requirements.
Windows is unable to verify the image integrity of the file \Device\HarddiskVolume3\Program Files (x86)\Symantec\Symantec Endpoint Protection\14.0.2349.0100.105\Bin\WSCSAvNotifier.exe because file hash could not be found on the system. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
