This program is a tool to remove the malicious worm(s)
that spread through exploiting the DCOM RPC vulnerability using TCP port 135.
This worm attempts to download the msblast.exe file to the %WinDir%\system32 directory and execute it.
Once executed it creates a hidden Cmd.exe remote shell that will listen on TCP port 4444,
allowing an attacker to issue remote commands on the infected system.
This tool was made to Automate the process of removing the worm from memory and all files related to it.

-------------------------------------------------------------------------
Directions:
1. Execute the file called DCOM2.exe
a. Deletes the registry values that have been added.
b. Terminates the W32.Blaster.Worm, W32.Blaster.B.Worm, and W32.Blaster.C.Worm viral processes.
c. Deletes the W32.Blaster.Worm, W32.Blaster.B.Worm and W32.Blaster.C.Worm files.
d. Deletes the dropped files.

I think removing msblast from your pc it too easy so you can do it manually smile.gif
As the article says the vers of msblast are quiet few...but the way of disinfection is always the same tongue.gif . The only thing you have to do is to shut the worm from the proccess then open regedit and delete the keys that article says :
