Double-check Windows Update
The worm weasels into computer systems through a Windows vulnerability that was patched last October, and once in place it interferes with the Windows Update system, to protect itself. So, verify that your system is up to date. XP users should launch Internet Explorer (no other browser will do), visit www.windowsupdate.com, and click the "Review your update history" link. Vista users should launch Windows Update from the Start menu and click the "View update history" link. In particular, you want to see KB958644 in the list—that's Conficker's entry point. If your latest update is any older than March 2009, that's not good. Go back to the main Windows Update page and install all critical and security updates.

Turn Off AutoRun
Sure, it's convenient that CDs and DVDs automatically launch their programs when you put them in. You may even be happy to see the window that asks what you want to do when you insert a USB key. But Conficker and other worms subvert this handy feature to spread their infestation. Use a Conficker-tainted USB key to share pictures or music with a friend, and you're sharing the malware, too. The feature's convenience just isn't worth that risk. Here are instructions to turn off AutoRun.

Update Your Protection
It goes without saying that you should always keep your security software and malware definitions up to date. Don't just rely on automatic updates, as the worm has been known to interfere with these. Dig into your security software and manually launch an update, then watch to make sure it completes the process successfully. Now launch a full system scan.
