To date, security researchers have discovered two variants of the worm in the wild.

Win32/Conficker.B might spread through file sharing and via removable drives, such as USB drives (also known as thumb drives). The worm adds a file to the removable drive so that when the drive is used, the AutoPlay dialog will show one additional option.

The Conficker worm can also disable important services on your computer.

In the screenshot of the Autoplay dialog box below, the option Open folder to view files — Publisher not specified was added by the worm. The highlighted option — Open folder to view files — using Windows Explorer is the option that Windows provides and the option you should use.

If you select the first option, the worm executes and can begin to spread itself to other computers.
