You need to know how to uninstall the Norton AntiVirus Corporate Edition (NAVCE) Windows 95/98/Me client manually.


Solution




Before you begin:

This document is for those occasions when, due to an error or some other reason, you must uninstall NAVCE manually, rather than use Add/Remove Programs.

This document describes how to manually remove NAVCE from the following three places:
  • The registry
  • The Start menu
  • The hard drive

Remove NAVCE from the registry


WARNING: We strongly recommend that you back up the system registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Please make sure that you modify only the keys specified. See the document Backing up the Windows registry before proceeding.



With the registry backed up, you are now ready to edit the registry. You can navigate through the registry either with the mouse (by clicking the plus and minus signs), or with the arrow keys (up/down to move up and down, left/right to collapse/expand a branch).

To remove NAVCE from the registry:
Open the Registry Editor, and then navigate to the following registry keys:
    • HKEY_CLASSES_ROOT\*\Shellex\ContextMenuHandlers\LDVPMenu
      Right-click LDVPMenu, and then click Delete.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Intel\DLLUsage\VP6
      Right-click VP6, and then click Delete.
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
      Right-click vptray in the right side, and then click Delete.
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
      Right-click Defwatch, and then click Delete.
      Right-click Rtvscan, and then click Delete.


      Note: The removal of the following subkey only applies to NAVCE 7.0x.


    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\Norton AntiVirus Corporate Edition
      Right-click Norton AntiVirus Corporate Edition, and then click Delete.


      Note: This registry key should be removed for all versions of NAVCE when Add/Remove programs does not uninstall NAVCE correctly.


    • Highlight "My Computer" in the left pane, click Edit in the menu bar, click Find, and then do a search for each of the following two keys:
      74BE21DBFDBD3D11EBAE000ACC725290
      VirusProtect6


      Delete every found instance of the above keys.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Management\ARPCache\

      Delete the subkey: {BD12EB47-DBDF-11D3-BEEA-00A0CC272509}
    • For Windows 9x computers with NAVCE 7.5 client installed, navigate to the following registry key:

      HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

      Delete the subkey: {BD12EB47-DBDF-11D3-BEEA-00A0CC272509}


      Note: The following key should only be removed if NAVCE is the only Symantec product installed.

    • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\Symevnt
      Right-click Symevnt, and then click on Delete.
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
      Delete the RTVSCN95 entry.
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
      Delete the LiveUpdate entry.
NAVCE is now disabled. However, there will be traces of the program still in the registry. You must restart the computer for the registry changes to take effect.
