Motor de filtrado de base no se encuentra. Solución

Ayer estábamos instalando el antivirus Avast en un ordenador y nos apareció un error extraño “Motor de filtrado de base no se encuentra“. 
Este es un servicio que debería estar instalado y no estaba…obviamente algún virus lo habrá deshabilitado.

Afortunadamente Eset tiene una herramienta para resolverlo y parece ser que el causante es un tal Sirefef, un troyano muy majo que entre otros estragos quita este servicio.

Para arreglarlo tenéis que ir a este enlace, descargar de la parte II la herramienta ESET SirefefCleaner y ejecutarla como indican los pasos. Las ventanas que se abren te indican si tienes Sirefef en tu ordenador y te pregunta si quieres eliminarlo (obvia la respuesta).

Después reinicia el ordenador y verás que puedes reinstalar el Avast porque ya tienes ese servicio instalado.
