ACAD illegal operation 1

[sbnak1]

Today I downloaded the Norton Anti Virus 2003 from the Symantec Website. Now it seems that when I try to open my AutoCAD 2002 from the desktop I get this message:

ACAD caused an invalid page fault in
module AC1ST15.DLL at 018f:65fe1e3b.

What did I do?, becuase I was working on AutoCAD with no problems yesterday. It wasnt until after I had installed the Anti-virus that this came up. I cant even start AutoCAD at this moment.

Do I have to re-install Autocad2002 or does anybody know how I can fix this without doing that?

Thank you for your help

You will need to download a library file update from Autodesk. Here is the info and file.
