Tengo problemas con mi PC. De repente se pone lentísima y no me deja abrir los íconos del escritorio y carga Dr. Watson. Sospecho del SE.dll o alguna variación. Tengo cargado el BHO Deamon y me detecta el ntwg.dll, lo elimino con HijackThis v1.99.1 y me carga otro con diferente nombre, pero con las mismas consecuencias.
