     Reading the reports charitably, I would suspect that the Windows
     malware
     delivery mechanism might have been transported to the ISS, but would
     have been inactive there in the absence of a Step7 installation for
     the
     intermediate stage to infect.

   I hadn't thought they'd write it that way. In this way it makes sense.
   Thank you for your response.
