Mydoom A, B, and C (Doomjuice) Worm Removal Tool

Feb 10, 2004 10:41AM PST

Date Published: 2/9/2004
Version: 1.0

Overview
This tool will help to remove the Mydoom.A, Mydoom.B, and Mydoom.C (aka "Doomjuice") worms from infected systems. Once the tool has run?after the End-User License Agreement (EULA) is accepted?it automatically checks for infection and removes any of the targeted worms that are found. If a machine is infected with the Mydoom.B worm, the tool will also provide the user with the default version of the hosts file and set the "read-only" attribute for that file. This action will allow the user to visit previously-blocked Microsoft and antivirus websites.

After running, the tool displays a message describing the outcome of the detection and removal process. The tool can be safely deleted after it has run. Also, the tool creates a log file named doomcln.log in the %WINDIR%\debug folder.

This tool will not:

Detect or remove any viruses or worms other than Mydoom.A, Mydoom.B, and Mydoom.C (aka "Doomjuice")

Detect or remove future variants of Mydoom or Doomjuice

Prevent the machine from being re-infected with Mydoom if, for example, an infected e-mail attachment is re-executed

Detect or remove malware that exists on a system as a result of the backdoor component created by Mydoom.A, Mydoom.B, and Mydoom.C
Delete any e-mail that contains Mydoom.A, Mydoom.B, or Mydoom.C

The user must be an administrator to run this tool.

This tool is an updated version of the Mydoom tool posted on 2/5/04. It is recommended that all users run this new version to ensure that they are not infected with Mydoom.A, Mydoom.B, or Mydoom.C (aka "Doomjuice").
