Conficker, Kido or Downadup

This virus known by all of the above names seems to be causing quite a bit of havoc in the computer world. This brings two questions, firstly, I have auto update enabled on my machines for Windows updates, will the patch that is mentioned here be auto downloaded and secondly, I have McAfee online, will they have patched me too or are they all playing catchup?
Thanks
