The client is the last line of defense, so (generally) has to be
the one you put the hard yards into. Far too many people make the
mistake of going the "easy route" of grabbing server (or worse,
just "gateway server") virus scanners and then kicking back,
believing they have nailed the problem -- until the next cunning
security exploit or previously unthought of "sneak around AV"
trick comes out. Although it is not always the case, often these
"tricks" are still detected on the desktop by heuristics and/or
generic detection technologies after the "cunning trick" executes
and unpacks the actual malware code.

The point -- don't overestimate the value of solutions at each of
the locations, no matter how much a vendor may over- or under-sell
