It is intended for use in exceptional situations only (to quote Sophos Bootable Anti-Virus: download and CD creation instructions: Do not use this tool until all other options have been exhausted).

The quoted article also states: Once the virus outbreak has been contained and eliminated from your network, please delete the downloaded program and destroy the CD. Therefore the tool and its associated process have been deliberately to discourage routine use.
