going by the details in your "details" link, that part about returning
windows to it's out-of-the-box configuration seems like a bit of an
exaggeration/misinterpretation. you need to use the windows recovery
console to restore the MBR. that's good advice for any current malware that
happens to affect the MBR.

what seems to be notable about this particular piece of malware is not that
it gets in the MBR but that it protect itself once there - but only so far
as any piece of malware can. it can't protect itself when it's not active,
that's why use of the recovery console is required.
