Bah.  It IS a Symantec product problem because they were relying on an
intrustable infrastructure rather than using a mechanism to actually
authenticate the Live Update server or the data it provides to the
client like they do with the newer version.  Blaming the
infrastructure is disingenuous at best.  If a system is to be secure,
the trustability and validity of ALL externally provided input must be
considered.
