Do you mean Norton Anti-Virus form Symantec or something else ?

The NAV 2003 removal tool can be downloaded here: ftp://ftp.symantec.com/misc/consumer/Rnav2003.exe
Manual Removal NAV 2003 or earlier - Manual Removal NAV 2003 or earlier
A link worth looking at, which is a program removal tool that can remove the remnants of a number of different Norton Programs:

If it is something directly from Symantec then you really need to find out the exact program and do a google search for symantec ?? removal tool (where ?? is the AV name).
