We published the second Security Intelligence Report. Now, you might ask, why this is significant. Think about the data sources, we build the report on: Since FY05 the Malicious Software Removal Tool was run over 5 Billion times and removed more than 27 Million of Malware. Since November 2005 when we launched the Beta, Windows Live Online Safety Scanner was downloaded more than 15 Million times. Now, we collect information about the OS we are running on, the Service Packs and the Patch Level as well as the locale. We do not collect any Personal Identifiable Information - obviously. But this gives us a pretty broad bases to look at - and there are some really interesting figures in there.
