Outlook vulnerability

It has been a long time since a vulnerability on Microsoft Outlook was disclosed. This time MS08-015 is one of those that facilitates the spreading of malware, as it makes easier to run unathorized code. Some people learn that they can click on the links but they can't click on "yes" when being asked if an application can be executed. This vulnerability can take them off guard.I would expect to see on those nice reports that Microsoft produces periodically how the Vista users will be impacted by this versus XP users. Everybody is talking about the bad side of the UAC features, but I'm still waiting to see good news about its results on malware activity. Hope to see something about it soon.
