Worm Attack: 9 Million PCs Hit

Kevin R. Smith

The smart folks doing research at Finnish security company F-Secure estimated another 6.5 million Windows PCs have been infected by Downadup / Conflicker worm... in the past four days.

That adds to the 2 million plus that were already infected.

If you haven't yet heard the story on this worm, known as Downadup or Conficker, it exploits a bug in the Windows Server service. Affected operating systems include:

  • Windows 2000 (all versions)
  • Windows XP (all versions)
  • Windows Vista (all versions)
  • Windows Server 2003
  • Windows Server 2008

Worst thing of all about their estimates: even they say they're conservative. Usually in cases like this they really are.

If your computer has been infected with Donwadup/Conflicker, here's where to get Microsoft Downadup/Conficker patch.

They've also issued an update to their Malicious Software Removal Tool.
