When trying to open Sophos on the client (by right clicking the system tray icon and selecting ‘Open Sophos Antivirus’) you get the following error:
You do not have sufficient privileges to run the Sophos Anti-Virus main application.
You are not a member of one of the Sophos groups. In order to be able to launch this application, you must be a member of SophosAdministrator, SophosPowerUser or SophosUser group. Please contact the Administrator.
Fix can be found on the Sophos site:
However if this does not work (as it didn’t for me) you will need to reinstall Sophos on that client. Remember to delete it off the server too from the enterprise console.
