W32.Blaster.Worm Removal Tool
Discovered on: August 11, 2003
Last Updated on: August 11, 2003 08:01:58 PM PDT





Symantec Security Response has developed a removal tool to clean the W32.Blaster.Worm infections.

What the tool does

The W32.Blaster.Worm Removal Tool does the following:

Terminates the W32.Blaster.Worm viral processes.
Deletes the W32.Blaster.Worm files.
Deletes the dropped files.
Deletes the registry values that the worm added.

Command-line switches available with this tool



Switch

Description

/HELP, /H, /?
Displays the help message.

/NOFIXREG
Disables the registry repair. (We do not recommend using this switch.)

/SILENT, /S
Enables the silent mode.

/LOG=<path name>
Creates a log file where <path name> is the location in which to store the tool's output. By default, this switch creates the log file, FixBlast.log, within the same folder from which the removal tool was executed.

/MAPPED
Scans the mapped network drives. (We do not recommend using this switch. Refer to the Notes below.)

/START
Forces the tool to immediately start scanning.

/EXCLUDE=<path>
Excludes the specified <path> from scanning. (We do not recommend using this switch.)

NOTE: Using the /MAPPED switch does not ensure the complete removal of the virus on the remote computer, because:
Scanning the mapped drives scans the mapped folders only. This action may not include all the folders on the remote computer, leading to missed detections.
If a viral file is detected on the mapped drive, the removal will fail if a program on the remote computer uses this file.

For these reasons, run the tool on every computer.

Obtaining and running the tool

NOTE: You need administrative rights to run this tool on Windows 2000, or Windows XP.
Download the FixBlast.exe file from:

http://securityresponse.symantec.com/avcenter/FixBlast.exe

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).
To check the authenticity of the digital signature, refer to the section, "Digital signature."
Close all the running programs before running the tool.
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.


Double-click the FixBlast.exe file to start the removal tool.
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."


Restart the computer.
Run the removal tool again to ensure that the system is clean.
If you are running Windows XP, then re-enable System Restore.
Run LiveUpdate to make sure that you are using the most current virus definitions.

When the tool has finished running, you will see a message indicating whether W32.Blaster.Worm infected the computer. In the case of a worm removal, the program displays the following results:
Total number of the scanned files
Number of deleted files
Number of terminated viral processes
Number of fixed registry entries

Digital signature
FixBlast.exe is digitally signed. Symantec recommends that you only use copies of FixBlast.exe that have been directly downloaded from the Symantec Security Response Web site. To check the authenticity of the digital signature, follow these steps:
Go to http://securityresponse.symantec.com/avcenter/chktrust.exe.
Download and save the Chktrust.exe file to the same folder where you saved FixBlast.exe (for example, C:\Downloads).
Depending on your operating system, do one of the following:
Click Start, point to Programs, and then click MS-DOS Prompt.
Click Start, point to Programs, click Accessories, and then click Command Prompt.


Change to the folder where FixBlast.exe and Chktrust.exe are stored, and then type:

chktrust -i FixBlast.exe

For example, if you saved the file to the C:\Downloads folder, you would enter the following commands:

cd\
cd downloads
chktrust -i FixBlast.exe

Press Enter after typing each command. If the digital signature is valid, you will see the following:

NOTES:
The date and time displayed in this dialog box will be adjusted to your time zone if your computer is not set to the Pacific time zone.
If you are using Daylight Saving time, the displayed time will be exactly one hour earlier.
If this dialog box does not appear, there are two possible reasons:
The tool is not from Symantec. Unless you are sure that the tool is legitimate and that you downloaded it from the legitimate Symantec Web site, do not run it.
The tool is from Symantec and is legitimate, however, your operating system was previously instructed to always trust content from Symantec. For information on this and how to view the confirmation dialog again, read the document "How to restore the Publisher Authenticity confirmation dialog box."


Click Yes to close the dialog box.


Type Exit, and then press Enter. This will close the MS-DOS session.

System Restore option in Windows Me/XP
Users of Windows Me and Windows XP should temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, in some cases, online scanners may detect a threat in the System Restore folder even though you scanned your computer with an antivirus program and did not find any infected files.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:
How to disable or enable Windows Me System Restore.
How to turn off or turn on Windows XP System Restore.

For additional information and an alternative to disabling Windows Me System Restore, read the Microsoft Knowledge Base article, "Antivirus Tools Cannot Clean Infected Files in the _Restore Folder (Q263455)."

How to run the tool from a floppy disk
Insert the floppy disk, which contains the FixBlast.exe file, in the floppy disk drive.
Click Start, and then click Run.
Type the following:

a:\FixBlast.exe

and then click OK:

NOTES:
There are no spaces in the command, a:\FixBlast.exe.
If you are using Windows Me and System Restore remains enabled, you will see a warning message. You can choose to run the removal tool with the System Restore option enabled or exit the removal tool.


Click Start to begin the process, and then allow the tool to run.
If you are using Windows Me, then re-enable System Restore.

Perro virus! ke berraco pa ser infeccioso! ayer escuche por primera vez de el y esta mañana ya estaba embalado buscando como kitarlo... gracias a dios ya monte el patch y 0 errores... gracias a dios solo se limita a reiniciar y no me borro cositas o me daño archivos de mi HD, porke ahi si!
 
noticias 3d
El virus ejecuta los ficheros "mblast.exe" y "tftp.exe" e infecta a todos los PC's de internet que tengan el puerto TCP/135 abierto y no tengan el parche instalado.

lol gracias clan prozac por la ayuda me ubiera quedado buscando ese patch gracias mejos !
 
A mi me cogio tipo 11 pm y ya estaba que tiraba el pc por la ventana :S cuando me di cuenta me dijo Cyberkiller que era un virus :D
Tarde pero se actualizo el AV y listo.
Pero que virus tan ******************.
 
bueno... y puedo ejecutar el patch sin que el virus se haya manifestado???
El norton lo recnoce pero el pc nunca se ha reiniciado.. se puede?
 
Hiada actualiza tu antivirus. Si tienes una utilidad como el LiveUpdate, por ahi no. Es mejor bajarse las actualizaciones de las paginas directamente, k esas las actualizan (valga la redundancia) cada dia.

A mi no me ha cogido eso, afortunadamente. Pero si salio algo asi que entra por el tftp, k ese deja entrar relativamente facil, de aki en adelante estamos j*******

bueno... y puedo ejecutar el patch sin que el virus se haya manifestado???
El norton lo recnoce pero el pc nunca se ha reiniciado.. se puede?

El norton reconce el virus en si mas no elimina el problema de seguirdad de Win; el patch es para eliminar este problema de seguridad


Personalmente, ese virus si me a parecido de las mejores cosas que han salido.
 
hmm el Norton 2003 no lo cogio, y si se me aparecio la cosa de reiniciar la makina, baje el fix y segun eso no encontro nada, tengo el norton recien actualizado de ayer

Acabe de instalar el Norton Corporate a ver...
 
a mi me molesto toda una tarde, pero la verdad no sabia que era un virus... mi norton 2003 no lo detecta... pero yo no tuve que borrarlo.. solo actualice los security updates de windows y ya no volvio a suceder... sera que el virus sigue en mi maquina... ustedes que me recomiendan...??
 
lo mas raro es que solo me molestaba cuando me conectaba a internet, de resto no molestaba y lo mas raro de todo solo jodia si me conectaba a internet por modem de 56k porque por cable modem tampoco jodia... que raro.!!!!
 
.... que bueno tener activado el firewall del router...


haber si usamos el windows update...
 
Aunque el firewall no permite que el virus no entre a la red desde Inet, si el virus entra por otro medio "Alguien trajo su laptop infectada", el virus se esparciera por la red local si mayor dificultad, para eso lo mejor es estar bien atento a windows update y bajar todo lo que saque, nada de esperar a un service pack.
 
primero abran el msconfig por ejecutar y eliminen la linea ke carga el msblast al inicio, ahora ejecuten el administrador de procesos (ctrl+alt+supr) y cierren el proceso msblast. Busken el archivo msblast en el disco duro y borrenlo... instalen el patch de ms y listo... asi me libre yo de esa joda...
 
menos mal que no fue tan grave imaginese que formatiara todo
eso si se seria grave lol
 
bueno.. la verdad apenas me entero, aunque por ahi un amigo me comento.

pero esta muy bueno el virusete.
