The c++ compiler and runtime libraries are common enough that the 
antivirus realizes it is nothing special, but since D is more 
obscure it just flags it as abnormal and does further checks. 
(more obscure C++ compilers can do the same thing).

Walter has written Microsoft and they have OK'd it before, but 
then one side or the other updates and then they are out of whack 
again :(
