Hi, please help I am having a problem I have never seen before.

The Problem:
Whenever the PC starts it launches the Win98 Set up Wizard that asks you
your name, company name, and product key code. (I've not entered the info as
I'm not sure what it will do to the existing files.) When I hit Cancel the PC
says it can not launch Windows and shuts down. This PC has worked for years.

What has changes/happened:
I have a win98 PC and was trying to install an upgrade to Norton Internet
Security 2005. It waned me that Norton Antivirus was installed and said that
that had to be removed through Add/Remove Programs before installing. I
uninstalled NAV 2001 through the control panel. When it warned about deleting
shared files, I said to leave all on the PC. After the uninstall, the PC
needed to reboot. After the reboot, when the PC powers up instead of
displaying the Windows logon box asking for User and Password, it launches a
wizard that says it's the Win98 Set-up Utility and asks for name, company,
and Product Key Code. I have not completed the wizard because (1) it should
not be launched and (2) I'm not sure what it's going to do to the files
already on the PC.

Additional Information:
The PC will load in Safe Mode and all user and program files that I can
identify seem to be present. But. obviously something has been deleted or
corrupted. The question is what?

Question:
What should I do to fix this so that when Win98 launches it will not think
it needs to run set-up, but just allow my user to login and use their PC.

Thanks.
