This tool helps to remove the Mydoom.A, Mydoom.B, Mydoom.E, Mydoom.F, Mydoom.G, Mydoom.J, Mydoom.L, Mydoom.O, Zindos.A, Doomjuice.A, 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 also provides the user with the default version of the hosts file and set the "read-only" attribute for that file. This action enables the user to visit previously-blocked Microsoft and antivirus Web sites.
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.
