unable to re-install Norton AntiVirus - valid digital signature not found

After the nightmare to remove a bunch adware (TV Media, eZula, Power
Scan.... over 20+ items), I was unable to start Norton Antivirus 2003 in my
Dell Windows XP Prof system - "Norton AntiVirus has encountered an internal
program error. Uninstall and re-install Norton AntiVirus (3002,1530)".

So I uninstall and re-install this Norton AntiVirus 2003.
At the end of the installation I get this message:

Symantac CCApp "A valid digital signature was not found for this component.
NAVProd" (1002,2)

Following Norton AntiVirus knowledgebase instructions, I done:
1. uninstall the Norton Antivirus again (control panel / remove program).
2. get online using Symantac online Security Check and scan all hard drives.
Found no virus.
2. boot to safe mode and run FixKlex.com. Found no W32.Klex.E worm
3. turn off system restore (MY computer / property)
4. run regsvr32 wintrust.dll. DllRegisterServerSucceeded.
5. Make sure that the Windows Cryptographic service is running
6. download and install the Microsoft Windows Script 5.6 for Windows 2000
and XP

I done these according to Symantac instructions:

Well, still trying to reinstall Norton AntiVirus 2003 and Norton SystemWork
2003, same error message, same problem, unable to run Antivirus after
installation.

Any advise and help is much appreciated.

I had the same problem but after going through all the steps I was up
against a brick wall with Norton as it was only a limited period
installation with a new PC and had to buy There is no other way. Sorry!
