Clients using Symantec Antivirus Corporate Edition requires a password while uninstalling the client. The default password out of the box is symantec. If you have changed this password within the Symantec System Center - then you need to use that password. If you have changed the uninstall password and you no longer have access to this password - well then shame on you. Fortunately there is a workaround:
1) Open Regedit
2) Browse to HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\ VirusProtect6\CurrentVersion\Administrator Only\Security\
3) Change the value for this key from 1 to 0
useVPuninstallpassword
4) Close the registry and retry the uninstall
