Voilà, la bête a un nom : W32.Blaster.Worm
Informations symantec :
http://securityresponse.symantec.co...aster.worm.html
Citation:
W32.Blaster.Worm is a worm that will exploit the DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026) using TCP port 135. This worm will attempt to download and run the Msblast.exe file.
Block access to TCP port 4444 at the firewall level, and then block the following ports, if they do not use the applications listed:
TCP Port 135, "DCOM RPC"
UDP Port 69, "TFTP"
The worm also attempts to perform a Denial of Service (DoS) on windowsupdate.com. This is an attempt to prevent you from applying a patch on your computer against the DCOM RPC vulnerability.

Même si vous avez, installé le patch, il faut faire du nettoyage !

Obtaining and running the tool
NOTE: You need administrative rights to run this tool on Windows 2000, or Windows XP.
1- Download the FixBlast.exe file from:
http://securityresponse.symantec.co...er/FixBlast.exe
2- Save the file to a convenient location, such as your downloads folder or the Windows Desktop (or removable media that is known to be uninfected, if possible).
3- To check the authenticity of the digital signature, refer to the section, "Digital signature."
4- Close all the running programs before running the tool.
5- If you are running Windows XP, then disable System Restore. Refer to the section, "System Restore option in Windows Me/XP," for additional details.
CAUTION: If you are running Windows XP, we strongly recommend that you do not skip this step. The removal procedure may be unsuccessful if Windows XP System Restore is not disabled, because Windows prevents outside programs from modifying System Restore.
6- Double-click the FixBlast.exe file to start the removal tool.
7- Click Start to begin the process, and then allow the tool to run.
NOTE: If, when running the tool, you see a message that the tool was not able to remove one or more files, run the tool in Safe mode. Shut down the computer, turn off the power, and wait 30 seconds. Restart the computer in Safe mode and run the tool again. All the Windows 32-bit operating systems, except Windows NT, can be restarted in Safe mode. For instructions, read the document "How to start the computer in Safe Mode."
8- Restart the computer.
9- Run the removal tool again to ensure that the system is clean.
10- If you are running Windows XP, then re-enable System Restore.
11- Run LiveUpdate to make sure that you are using the most current virus definitions.
