What Virustotal says about a suspicious attachment and AV products

I received a $50 iTunes gift certificate today as a zip file. Yay!

I uploaded it to Virustotal, and the result is below. If the formatting is lost, you can see the report here: http://shar.es/m6tDP

First, Virustotal told me that they already have seen this file. Next, very few AVs identified it as a threat. And at the risk of beating up on McAfee again, their gateway version with a May 6 def identified it, but their regular (?) version with a May 7 def did not! In all, only 8 of 41 identified it.

AVG, which is on my laptop, did not identify it either.

My question: what happened to AV companies sharing knowledge? I would
have thought in 24 hours at least all the big boys would have shared the
signature. A 20% detection rate is pretty bad. But as McAfee's left hand
does not know what its other left hand is doing, I guess I should not be
too surprised.
