arielle..... Which version of Norton are you using ........ I came across this ..........it may assist you ...
For unmanaged Norton AntiVirus CE installs, there is a GRC.DAT file available on Worf which will password protect the un-install of Norton AntiVirus CE version 9.x on a workstation. After installing Norton AntiVirus CE from the CD-ROM, FTP to worf.cc.mcgill.ca\sharedvol\pub\mcgill\navce\datfile, copy the GRC.DAT file from there to the \7.5 directory on NT/2000 workstations, or the \program files\Norton Antivirus directory on WIN9x workstations. The un-install of Norton AntiVirus CE version 9.x is now password protected.
Just had another thought ....... you are the computer administrator aren't you .
