Después modifica los siguientes valores del registro, para hacer que dicha carpeta sea compartida por otros usuarios de KaZaa e iMesh:

HKEY_CURRENT_USERSoftwareKAZAALocalContent
Dir0 = 012345:c:windowssystemdrivers32

HKEY_CURRENT_USERSoftwareiMeshClientLocalContent
Dir0 = 012345:c:windowssystemdrivers32

El gusano también intenta robar las claves de registro (CD keys), de cualquiera de los siguientes juegos que estuvieran instalados en la máquina infectada:

Battlefield 1942 - The Road to Rome
Counter-Strike
Half-Life
Neverwinter Nights
Project IGI 2
Rainbow Six III RavenShield

Unreal Tournament 2003

Finalmente, se puede conectar a determinado canal de IRC para avisar a un usuario remoto que la computadora ha sido infectada, y poder recibir instrucciones de parte de éste. Estas instrucciones le permiten ejecutar determinados comandos en forma remota, y realizar ataques de denegación de servicio (DoS) a determinadas direcciones.


Reparación manual

Para borrar manualmente el gusano, primero actualice sus antivirus con las últimas definiciones, luego siga estos pasos:

1. Reinicie Windows en modo a prueba de fallos, como se indica en este artículo:

Cómo iniciar su computadora en Modo a prueba de fallos.
http://www.vsantivirus.com/faq-modo-fallo.htm

2. Ejecute sus antivirus en modo escaneo, revisando todos sus discos duros.

3. Borre los archivos detectados como infectados por el virus.

4. Borre la carpeta DRIVERS32 y su contenido:

c:windowssystem32drivers32

NOTA: En algunos sistemas puede existir una carpeta DRIVERS que pertenece al sistema, tenga cuidado de no borrarla.


Editar el registro

1. Ejecute el editor de registro: Inicio, ejecutar, escriba REGEDIT y pulse ENTER

2. En el panel izquierdo del editor, pinche en el signo "+" hasta abrir la siguiente rama:

HKEY_LOCAL_MACHINE

3. Pinche en la carpeta "Run" y en el panel de la derecha, bajo la columna "Nombre", busque y borre la siguiente entrada:

IELoader32

4. En el panel izquierdo del editor, pinche en el signo "+" hasta abrir la siguiente rama:

HKEY_CURRENT_USER
Software
KAZAA

5. Pinche en la carpeta "LocalContent" y en el panel de la derecha, bajo la columna "Nombre", busque y borre la siguiente entrada:

Dir0 = 012345:c:windowssystemdrivers32

6. En el panel izquierdo del editor, pinche en el signo "+" hasta abrir la siguiente rama:

HKEY_CURRENT_USER
