How the Worm Spreads

The Autorun worm spreads by exploiting the autorun feature in Microsoft Windows. Once the infection begins, the worm will create several fake folders on any removable drives connected to the computer. The names of these folders are typically random letters and numbers. When someone attempts to view the contents of one of these folders, " this folder contains an autorun.inf file. To view the contents of this folder, you must enable the autorun feature. If the user clicks "Enable," the worm will be executed and will begin to copy itself to any other removable drives connected to the computer.

The worm will also create a fake autorun.inf file in each of the folders it makes. This file is used to execute the worm whenever the folder is opened automatically. The autorun worm can also spread through network shares. If a computer on a network has a shared drive that is not configured correctly, the worm can copy itself to the share and then spread it to other network computers.

Prevent infection from the Autorun worm by:

  • Disabling the autorun feature in Windows.
  • Being cautious of opening email attachments or running programs from removable drives.
  • Running a comprehensive scan with reliable anti-virus software to remove the worm and other malicious software if you suspect your computer is infected.

Beware of Shared Removable Devices
