The security update won’t necessarily help users who have already been infected with the bootkit as TDL4 blocks the Windows Update service on x86 machines. As a result, infected x86 machines won’t be able to download and install the patch automatically.

* Sorry, but I couldn't resist a Crosby reference. I was more than a little irritated over the weekend – see Faith, Hope, Charity and Manipulation - by Microsoft's use of the Japanese disaster to give the Bing search engine a little extra exposure using a chaintweet technique: How you can #SupportJapan – http://binged.it/fEh7iT.
