Problem is, there's always a risk (Score 1)

Even if the risk is so small as to be vanishing, the problem with this sort of rubbish (similarly to a lot of IT security consultant twaddle), is there's still a risk. Put another way, is there no risk at all that something from SETI could cause a problem on a PC...? Answer is, yes, there's a very small risk, but it is still a risk. For the PHB types (or journalists) who don't understand how to quantify risk, this can be something to panic about. I bet that more than one IT support person has been asked by his/her Guardian reading boss how SETI can be banned from the site because of this "issue". Anthony.
