    Mil gracias por esta solución, mi equipo quedo limpio del todo, cabe comentar que la pantalla queda un rato en negro al reinisiarla OTM, no se espanten como yo, dejen que termine el proceso. Y si es necesario hacer el paso 2, MBAM encontro otros troyanos que tenia mi sistema. Confien en esta solución. Saludos!!!!!!!!!!!!!!!!!!!
