error windows popup when outlook started

Hello,

Do you have any other solution besides delete 'extend.dat' file for below error ?

'The Add-in "Symantec Antivirus Outlook Protection" (C:\Program Files\Symantec\Symantec Endpoint Protection\12.1.6608.6300.105\Bin\vpmsece.dll) cannot be loaded and has been disabled by Outlook. Please contact the Add-in manufacturer for an update. If no update is available, please uninstall the Add-in.'

Thanks.
