This iframe injection is very old news, avast has been dealing with it for absolutely ages. Though there is a lot of other useful information.
Personally I don't care what domains they point to as that is really irrelevant as the payload could be on any domain and trying to block these domains is like shooting at a moving target. Frequently the domain is only live for a few days.
So it has to be the detection of the injected iframe and or blocking that iframe from running (firefox and noscript with block iframes enabled) that is a better prevention in my opinion.
