Exclusion in registry

Hi all,

I'm checking the exclusion policy. For this purpose, I connect to a server and check registry key : HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV

In my case, the AV does not exist. I try to uninstall, delete Symantec Key and reinstall the client but nothing is better : i've got an SID key and not the AV : HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\Content\{0F3370CC-CB7C-4976-9315-22E436B26137}

Does somenone can explain me why i have not got the AV entry and why i've got an SID instead ?

Thank you,

Olivier
