In the cases where Symantec AntiVirus server has been taken down and no longer exist, or the client computer has no access to company network, or the default client uninstall password does not work, the following hack will enable you to remove Symantec Antivirus without using a password:
Open Registry Editor (regedit).
Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\VirusProtect6\CurrentVersion\Administrator Only\Security\
Change the value for useVPuninstallpassword key from 1 to 0.
Exit Registry Editor and now you can uninstall Symantec AntiVirus Client.
The trick should work on most version of Symantec AntiVirus client or Norton AntiVirus Client, including version 7, 8, 9 or 10.
