Hola, me apunte a este foro hace unas horas. He hecho todos los paso que habeis indicado en diferentes respuestas que dais. Ya no se que hacer, pues esto siguiendo todos los pasos no se me va. Que debo hacer??

Muchas gracias a todos

Buenasss

Ejecuta la herramienta DelPSGuard (ahora elimina el archivo de mbuscas tambien ) en modo normal y seguro

Pasa el ad-Aware

Pega un log de HiJackthis

Ante todo, muchas gracias por responderme tan rapido. He hecho todos los pasos que me has comentado y ahora te pego el Log. Tengo la esperanza de que ya no me de mas la lata este mbuscas ....de todas formas sino volvere a preguntarte. Muchas gracias otra vez
