Personally I would call this report
Junk Science.
While within the very limited parameters described in it, it may be right it in no way implies that it is the definitive end work on the subject.
In the old days we had a saying that if the device wouldn't pass the test, rig the test so that the device passes. Those that did this where held in Low Regard and this report from the quick reading of it I did and the responses above I believe fall into this condition.
It is relying on a Layer of Software quite or most often turned off by the end user because it causes way too many False Positives. It may stop a lot of Infected Sites because they have Paid their Microsoft Tax and continue to but it will reject every site that doesn't contribute to Microsoft and their income stream. Incidently this is the majority of sites out there on the Net and not just those either paying Microsoft for the privilege or those sites run by Microsoft under the name Azure.
Also as mentioned above if you are on anything but High Speed Broadband this ups your Data Usage dramatically and kills any slower service from being useful. So how exactly could IE9 be considered as More Secure when the majority of the world have to have it turned off to get any sort of part way decent Internet Service that is able to load pages in under several minutes and access Web Pages that are not directly related to Microsoft in some way?
As things currently stand the vast majority outside of Major Population Centres even in the US would be balking at using things like this as their slow speed Internet is alread Bogged Down with too much Junk in the form of Scripts that are contained in the Page itself let alone a List Maintained by Microsoft that is constantly changing running on top of the various Web Sites that they want to visit.
It's reports like this that make people think that Scientists are all Charlatans who will give a response that the person paying the bills asks for which within the Limited Confines of the Parameters used is correct but totally meaningless to the great majority of users in the World. Scientifically it is possible to turn lead into gold but the value of the produced gold is far less than the cost of producing it and this report sounds very much to me at least that it's a Scientific Paper screaming out Turn Lead into Gold, Or Climate Scientist proves Global Warming isn't happening.
