We wrote several diaries about Conficker (or Downadup, depending on the AV tool you are using). F-Secure posted some interesting information about the number of infections which is almost certainly in millions (and who knows how many machines will stay infected as the owners will not even notice anything).
One of the reasons for infecting so many machines is that Conficker uses multiple infection vectors:
It exploits the MS08-068 vulnerability,
It brute forces Administrator passwords on local networks and spreads through ADMIN$ shares and finally
It infects removable devices and network shares by creating a special autorun.inf file and dropping its own DLL on the device.
Pint-size luxury and funky style
