Hi,

Step#1


> Download ComboFix from here (http://download.bleepingcomputer.com/sUBs/ComboFix.exe) and save it to your Desktop.
If you are unsure how ComboFix works please read this guide (http://www.bleepingcomputer.com/combofix/how-to-use-combofix) carefully.
note: ComboFix must be downloaded to your Desktop.

> Temporarily disable your AntiVirus program.
If you are unsure how to do this please read this (http://www.techsupportforum.com/forums/f50/how-to-disable-your-security-applications-490111.html) or this (http://www.bleepingcomputer.com/forums/topic114351.html) Instruction.

How to disable avast:

Note: Do not forget to turn on this option after the cleaning.



> Run ComboFix. Click on I Agree!
ComboFix will check if there is a newer version of ComboFix available.
Click Yes if prompted to download.

ComboFix will display DISCLAIMER OF WARRANTY ON SOFTWARE.
Click Yes to allow ComboFix to continue.

If Recovery Console is not installed, ComboFix will offer download & installation.
Click Yes to allow ComboFix to install Recovery Console.
Note:Do not mouse-click Combofix's window while it is running.
If you see a message like "Illegal operation attempted on a registry key that has been marked for deletion" just restart computer once more.


> When the tool is finished, it will produce a log report for you. (typical location: C:\ComboFix.txt )
  Attach log reports ( ComboFix.txt) back to topic.




******************************


Step#2


Please download zoek.exe (http://home.kpn.nl/stefsmeenk/zoek.exe/) and save it to your desktop.

Code: [Select]

Hola Javier.

Si necesitas ayuda en algo que no entiendas estare atento. Por los momentos sigue las instrucciones de magna86.

Translation of magna86's instructons.

Paso #1

1.) Descarga ComboFix (http://download.bleepingcomputer.com/sUBs/ComboFix.exe) a tu escritorio. Combofix tiene que ejecutarse desde el escritorio.

2.) Desactiva el modulo de defensa y los escudos de Avast!.

   a.) Abre Avast! > Opciones > Solucion de problemas > desmarca "Activar el modulo de defensa de avast!" > Aceptar.
   b.) Click derecho al icono de Avast! en tu barra de tareas > Control de los escudos de avast! > Desactivar permanentemente.

3.) Ejecuta ComboFix y clickea "I agree". Clickea "Yes" a todo lo que Combofix pregunte. Puede que instale una nueva version y lo mas seguro instalara una consola de recuperacion.

Mientras ComboFix se ejecuta o esta haciendo el analisis no muevas el raton o clickees nada .

Si te sale una alerta con "Illegal operation attempted on a registry key that has been marked for deletion" solo reinicia tu ordenador y hazlo saber aqui lo que paso.

4.) Cuando Combofix termine genera un reporte comummente en C:\ComboFix.txt . Por favor anexa el reporte en tu respuesta.

Paso # 2

1.) Descarga Zoek (http://home.kpn.nl/stefsmeenk/zoek.exe/) y guardalo en tu escritorio.

2.) Desactiva Avast! como lo hicistes arriba si los escudos o tu lo volvieron a activar y asegurate que los navegadores o el explorador de Windows esten cerrados.

3.) Ejecuta zoek.exe. Espera a que abra.

4.) Copia el codigo de abajo y pegalo en la caja o el espacio vacio de zoek.exe.
Code: [Select]
standardsearch;
5.) Clickea donde dice " RUN SCRIPT ". Cuando termine puede que pida reiniciar el ordenado y te dara un reporte "zoek-results.log". De cualquier forma salva el reporte para despues anexarlo en tu respuesta con el reporte de combofix. Si no genera el reporte automaticamente, lo puedes conseguir en C:\zoek\zoek-results.log.

Yo vengo ejecutando como habrás visto, el proceso propuesto por essexboy, AdwCleaner/MBAM/OTL/aswMBR...
pero aswMBR no pudo completar el scan, y aparece:
avast! Antirootkit dejó de funcionar
El programa dejó de funcionar correctamente por un problema. Windows cerrará el programa y le notificará si existe una solución.
AHÍ QUEDÉ.
Ahora, abandono todo este plan de ataque, y ejecuto las instrucciones de magna86?
El plan de magna, es para terminar con el virus, o es básicamente para estudiar los reportes y buscar la solución?
Al momento tengo prendido avast y ahora quedó el MBAM. Ambos avisan cada tanto que han bloqueado al virus.
Un dato: luego de una inactividad de mouse de 3min., cuando uno vuelve ya se encuentra con el aviso de avast y de MBAM.

COMBOFIX report
combofix se ejecutó, pidió restart, y finalizó con el reporte. Abro my documents, y saltó el error "illegal operation attempted on a registry key that has been...."
, reinicié y vuelve a estar todo operativo.
Veo que:
en ....user/AppData/Local/Temp/ la carpeta iswizar, donde estaban el wuaudit.exe y el dwm.exe, que bloqueaban avast y mbam, ha sido eliminada por ComboFix.

El combofix se ejecutó con el avast desactivado, pero olvidé desactivar el mbam. Espero que eso no haya interferido en este scan. Pareciera que no.

@ Magna86

Javier deactivated Avast! but forgot to deactivate MBAM.

@ Javier

No importa que te haya salido esa advertencia. Como te dije arriba solo reinicia y reportalo aqui como lo hicistes.

magna86 quiere que copies ese codigo en bloc de notas y lo salves como CFScript.txt. Despues lo arrastras hacia el icono de Combofix. Supuestamente se ejecutara y salva el reporte y lo anexas a tu siguiente respuesta.

Tambien con zoek.exe copia/pega su codigo nuevo y correlo pinchando "run script". El reporte lo anexas a tu respuesta con el de Combofix

Tranquilo. Magna ya localizo la infeccion. Los nuevos codigos que tienes que copiar son para eliminarla y resetear tus sitios y conecciones para terminar con las redirecciones. Tambien esta limpiando otra basura que encuentra.

Hi,
BB tool and his script is very sensitive. In case of BB script error, BB wants to say that the file or folder doesn't exist.

Try to run this BB script:


Code: [Select]
DeleteFile:
f:\usuarios\Javier V\AppData\Local\Temp\iswizard\dwm.exe
f:\usuarios\JAVIER~1\AppData\Local\Temp\iswizard\dwm.exe
DeleteFolder:

or just this one:


Code: [Select]
DeleteFile:
f:\usuarios\Javier V\AppData\Local\Temp\iswizard\dwm.exe
f:\usuarios\JAVIER~1\AppData\Local\Temp\iswizard\dwm.exe


If you fail again, run Combofix via created CFScript.

Hi,
This is new & fresh malware, if you have will, stay little bit on. I just need to find sources ...

1. Read guide for running RogueKiller from >> here (http://forum.avast.com/index.php?topic=53253.0) << and attach here all RK reports.

2. Delete all zoek logs ( delete all C:\zoek-results.log ). I don't want to mix with fresh logs.


3. Then run this zoek script:


Code: [Select]
{41525333-0076-A76A-76A7-7A786E7484D7};c
c:\program files (x86)\AskPartnerNetwork\Toolbar;fs

Leave for now zoek logs, we will delete them later if need be.

1.
Please download Malwarebytes AntiRootkit and save it to your desktop.
http://www.malwarebytes.org/products/mbar/

Full instructions how to use MBAR
http://www.bleepingcomputer.com/virus-removal/how-to-use-malwarebytes-anti-rootkit

-----------------------------------

2.Now you need to delete old ComboFix (drag&drop Combofix icon into recycle bin) and download fresh copy from here:
http://www.bleepingcomputer.com/download/combofix/
Run Combofix as you did before and attach here fresh Combofix.txt log

I tested the pc and no more virus messages!!!!! Good job, Magna!!!
I think you must run some final scripts. Don´t you?
I needed to repair-reinstall Revit (cad soft), due to some instabilities. Now seems to work fine.
Internet Explorer now working fine after a configuration restore.
BUT:
Skype, Skydrive, and google  drive, don´t start at the windows startup.
In all these cases I check "start with windows startup", I close the dialog box, I open again the dialog box, and it´s uncheked again.
I tried updating skype, and gets this error:

(I hope you understand my english)

Magna:
I tested my pc all these days, and all is running fine and quickly.
Except:
when I run an Avast full scan,after 15 minutes or more of initiated,  the system crashes with the typical blue screen...
There´s any fix for this?

There´s a lot of updates from windows, waiting for download.

From the software side, BSOD appears at the driver level. What causes it I don't know but we can check.



Download BlueScreenWiew tool from here:
http://www.nirsoft.net/utils/bluescreenview.zip

Double click on BlueScreenView.exe file to run the program.
When scanning is done, go Edit>Select All.
Go File>Save Selected Items, and save the report as BSOD.txt.

Attach BSOD.txt here.

@ javiervalero

BSOD log lists error type that often may couse hardware failure. But one minidump report indicates that the cause of BSOD is aswSP.sys driver, related to avast! Self Protection.
I would test the HDD drive too but this is already beyond the region of the avast forum and this topic.

I have a similar issue.

In addition to wuadit.exe and isiwizard.7z there is also dwn.exe under the same TEMP folder
Can you help me?

When I try to do the Malwarebytes Anti Rootkit scan it detects only 1 malware.




Avast no logra remover el Win32:BitCoinMiner-CA. Solo lo bloquea.
