Can't uninstall old version of Norton Antivirus (enterprise 10 or coporate 7.5).

Created: 24 Jun 2009 • Updated: 21 May 2010 | 9 comments

I have a server2000 with some old norton on it and I can't uninstall it. It's either enterprise 10.1 or coporate 7.5. The reason I don't know, is that I get strange errors when trying to uninstall.
I have tried to install an endpoint 11 client, but get an error that says that a install i allready in progress (it's really not). There is no entry under "add/remove programs" in windows, so that's out too. The only removal tool I found on the website, doesn't even start up.
If I try to intall an enterprise 10.1 (as I suspect that it is) I get an error 2318 about some ap0.edb file in a symantec corporate edition 7.5 folder. I haven't got the installationfiles for 7.5 to try, so I'm kind of lost here.

Please help!

Norton removal Utility can be downloaded from here

Manually delete these folders

C:\Program Files\Symantec or C:\Program Files\SAV or C:\Program Files\Norton
C:Program Files\Common Files\Symantec
C:\Documents and Settings\All Users\Application Data\Symantec

Note C: is your root drive so it might be diffrent
After removing these try installing SEP 11.0 or SAV 10.1

I'm not sure if it would work but you could try Revo uninstaller, it a free software.

Ask for the clean wipe version 3.3 and not the latest version(4.X) IF USING SAV.

You can use NoNav to uninstall previous version of symantec/norton antivirus.

Norton removal tool will not remove Corporate or Enterprise Editions. Also Cleanwipe needs to be used with proper guidance as incorrect usage it may result in loss of network connectivity. I am not sure about NoNav either.

Better way is to perform a manual uninstall.

> Stop the Symantec services ( Start > Run > Services.msc)
> Download the Windows Installer CleanUp utility from;en-us;290301
> Look for any entry which says Norton, Symantec, ccApp, ccCommon, SPBBC, LiveUpdate, etc and remove them.
> Restart the computer.
> Backup the registry & then remove Symantec related folders, if they are still present.
  e.g., HKEY_LOCAL_MACHINE\Software\Symantec
> Then try to delete the Symantec folders in the C: drive if they are present (drive where you have the old Norton/Symantec programs were installed)
   e.g.,  C:\Program Files\Symantec
            C:\Program Files\Common Files\Symantec Shared
            C:\Documents and Settings\All Users\Application Data\Symantec  (Application Data folder will be hidden)

> If you have difficulty in removing folders, try in safe mode.
> Restart the computer & then try installing Symantec Endpoint Protection.
> This has worked in most of the cases.
