[R] OT: virus affecting a list subscriber

[David Duffy]

I presume I am not alone in receiving return-to-sender mailings provoked
by a well known virus eg

r-core at isem.univ-montp2.fr

If one has not recently virus-checked one's computer recently, it might
be a good idea.  I *of course* run linux, so it can't be me ;)
