To remove Symantec Antivirus without using a password:
(this has been tried in Windows Vista, and surely works, not sure about any other Operating System)
2) Click the links such that you finally reach: HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\VirusProtect6\CurrentVersion\Administrator Only\Security\
3) Double click on the file: ‘UseVPuninstallpassword’ for this key from 1 to 0.
4) Close the registry and retry the uninstall, this time your computer will not ask for any uninstall password.
5) Thank him…. Zakaria Bin Abdur Rouf. I got this from his blog 🙂
