A DLL related to the Lotus Notes plug-in still loads with Lotus Notes, even after you remove Symantec Endpoint Protection's optional Lotus Notes Email Scanner

After uninstalling the Lotus Notes plugin, you find that Symantec-owned dll's are still being loaded (for example, nlnvp.dll).





The nlnvp.dll file is still available on the system and still referenced in the notes.ini file.

The plugin uninstallation does not remove the changes it made to the file.



This problem is fixed in Symantec Endpoint Protection 12.1 Release Update 3 (12.1 RU3). For information on how to obtain the latest build of Symantec Endpoint Protection, read ‘Obtaining the latest version of Symantec Endpoint Protection or Symantec Network Access Control

Should it not be immediately possible to upgrade, the workaround is to manually remove the remaining files associated with the plugin as well as editing the notes.ini file.
  1. Uninstall the Lotus Notes plugin from the PC.
  2. Turn off Tamper Protection (if dealing with SEP 12.x)
  3. Stop the SEP Client Service. (smc -stop)
  4. Navigate to the location of the nlnvp.dll file and delete it.
  5. Navigate to the location where notes.ini is stored and edit it, by removing the following line from the Notes.ini file:
    NSF_hooks=NLNVP   or   EXTMGR_ADDINS=NLNVP.DLL  (depending on the version)
