Norton 2003 help

Hi I have norton 2003 installed on win 98. Was running fine until my son opened mail and picked up w32. Pc now clean of virus but unable to load norton 2003 without this annoying 1004,1 error and 4002,519. did all that symantec suggested,but error still occurs : cannot import CrogramFiles\symantecshared\ccreg.dat..uninstall ,reinstall ,deleted "CC" files from symantec ...but still get msg
Settings alert! Some Symantec product settings have been changed by an unauthorized program. This can indicate that an attacker or a virus is attempting to disable your program. To avoid problems settings will be reverted to their previous configuration and the system will be restarted."

Is there somewhere in the registry that need to be edited manually?
can you help?

 

Frankly editing the registry with NIS 2003 is a disaster it hides everyware.
Your best bet is to follow the following procedure
Boot into safe mode
Uninstall NIS
Boot into normal mode
Delete the Norton Folders
Run in this order
Rnav2003
RnisUPG
SYMCLN
Reboot and then try a new install.
You could also use JV16 reg cleaner if you still have problems.
The basic instructions are also given in Section 3 of this Symantec Procedure

 

thank you very much for your help, those instructions were bang on I am up and using 2003 once again ....many thanks
