Hola a todos! Yo soy nuevo en el foro y espero que mi mensaje llegue a la seccion correcta.
Hace dos semanas sufri el ataque del virus "hacktool" y del Spysheriff con mucha dificultad he podido anular a estos bichos, pero despues de esto han quedado algunas funciones del ordenador afectadas.El program antivirus Norton me avisa que hay una aplicacion que corregir la de "activar la funcion de actualizaciones automaticas en windows XP" y cuando ejecuto la orden en la ficha de actualizaciones automaticas de propiedades del sistema se activa solo unos minutos y despues se desactiva por si mismo.Me da la sensacion que todavia quedan restos de los bichos que dificultan el normal funcionamiento del ordenador.
Recurro a uds. para poder solucionar este problema.
Muchas gracias de antemano.
