These "viruses buried deep in the OS" are commonly known as rootkits. Looks like MSFT is trying to commercialize the research behind "Strider" (http://research.microsoft.com/en-us/um/redmond/projects/strider/rootkit/ http://research.microsoft.com/en-us/um/redmond/projects/stri...), but it's a bit hard to say for sure, based on the article's use of very non-technical vocabulary. Doesn't a PXE just make the whole boot process even more baroque, and prone to allowing bad guys to hide rootkits even easier?
