Hola, en primer lugar dar las gracias por todo el trabajo que hacéis. Y mi mas sincera gratitud por dedicarme vuestro tiempo.
Desde hace una semana, intenté arreglar el ordenador del IE Antispywere.Creo que lo logré con vuestra ayuda,leyendo casos similares del foro.
Pero mi problema persiste,y esta vez tanto mi explorer como firefox, en la casilla del buscador de la derecha, me direcciona a otras busquedas como paginas de casinos,webcams privados...etc. A parte también me saltan algunos pop-ups.Os agradezco de nuevo vuestra ayuda, aqui os dejo el reporte del Hijackthis:
