Other possibilities, also on a Microsoft site are
the Microsoft Windows Malicious Software Removal Tool (KB 890830) available in both 32 and 64 bit versions and there is also the Microsoft Safety Scanner, an online tool. I realize they are not the same, as pickleman has noted as a standalone version of MS Essentials but FWIW.
BTW, I posted this information the same day the article came out complete with links to each of these download sites. Although the links are completely legit, apparently the posting did not get the approval needed to appear here. I waited 24 hours and repeated the posting but it also has not appeared. Here's hoping this posting today is not blocked/censored/whatever.
