Microsoft Mydoom (A, B) and Doomjuice (A, B) Worm Removal Tool will help to remove the Mydoom.A, Mydoom.B, Doomjuice.A (aka "MyDoom.C"), and Doomjuice.B 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.
