How about starting the machine in safe mode? Does that work? If so, can you have them remove the latest DAT file? If not, can you ahve them remove the antivirus and then talk them through re-installing?
Last known config? Does that restore the dat to the old version?
Have you tried speaking to Mcaffee about this at all? Are they working on a DAT update or patch? If so, when its released, can you boot to safe mode and install it?
If the machine starts and simply starts shutting down, have the user run the command "shutdown -a" as mentioned above. Does that stop it from restarting?
