Figure 1-1

Solution

To resolve this issue, follow the steps in the following Knowledgebase article:

Exclude files or folders from scanning in ESET Windows home products

In step 5, create exclusions for:

\Device\HarddiskVolume1\EFI\Microsoft\Boot\BCD
\Device\HarddiskVolume1\EFI\Microsoft\Boot\BCD.LOG
\Device\HarddiskVolume1\EFI\Microsoft\Boot\bootmgfw.efi
%WINDIR%\system32\winload.efi

Exclusions for Microsoft Windows Server

Exclusions:

\Device\HarddiskVolume(%number%)\EFI\Microsoft\Boot\BCD
\Device\HarddiskVolume(%number%)\EFI\Microsoft\Boot\BCD.LOG
\Device\HarddiskVolume(%number%)\EFI\Microsoft\Boot\bootmgfw.efi
\\?\GLOBALROOT\Device\HarddiskVolume(%number%)\EFI\Microsoft\Boot\BCD
\\?\GLOBALROOT\Device\HarddiskVolume(%number%)\EFI\Microsoft\Boot\BCD.LOG
\\?\GLOBALROOT\Device\HarddiskVolume(%number%)\EFI\Microsoft\Boot\bootmgfw.efi
%WINDIR%\system32\winload.efi

If you are using Volume Shadow Copy, exclude also:

\Device\HarddiskVolumeShadowCopy(%number%)\*

Processes exclusions:

%WINDIR%\System32\wbengine.exe
%WINDIR%\System32\wbadmin.exe
%WINDIR%\System32\vssvc.exe

Volume of exclusion paths can vary

In the above exclusion paths, the volume can vary. The correct volume can be found in the registry at “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\hivelist”.

In this example, the USB drive is drive letter I. The exclusion would be created for I:\EFI\Microsoft\Boot\BCD
