t turns out that the TDL3 rootkit infection is related to the BSOD. See here: http://searchsecurity.techtarget.com/news/...1381423,00.html
PCs that are infected with the rootkit and run the patch (served by Windows Update) become unbootable!
The number of affected PCs tells us something about how widely spread the TDL3 rootkit is.
Statistics from our Scan Cloud:
Since November 30, Hitman Pro removed TDL3 infections from over 16.000 computers.
Interesting detail: 74.8% of those PCs were running an up-to-date AV.
That tells us how good this rootkit is in staying undetected or how difficult it is to remove this infection. TDL3 infects the hard disk driver (usually atapi.sys) and once loaded it serves the OS the uninfected driver, fooling most AVs as they see nothing wrong with the driver.
