Cleaning this new variant is difficult as some new techniques used by the virus writer lock down security of infected files, (blocks access to files using special registry settings), so that you have to clean in SAFE MODE until McAfee releases it's next DAT file (which will reset file access permissions in the registry to allow direct cleaning).


Due to the nature in which this virus operates once a machine is successfully infected, read-access to its file may be denied. The AV scanner will not be able to detect the file in this case. Because of this, if a machine is suspected to be infected, users are recommended to follow the procedure below:

Reboot the system into Safe Mode (hit the F8 key as soon as the Starting Windows text is displayed, choose Safe Mode.
Run a system scan using the specified engine/DATs.
Delete files flagged as infected
Restart machine in default mode.
