Microsoft Zapper for Mydoom, Zindos, and Doomjuice

Microsoft has a virus removal tool (Zapper) to help users clean up from the recent Mydoom, Zindos and Doomjuice worm attacks.  This small program, 120 kilobyte to download, has been programmed to identify and zap 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.  Once the tool has run, it would check for infection and remove any of the targeted worms it finds.
