HOla y gracias por tu respuesta!
Te cuento que hice lo siguiente... descargue el NOD 32 e inicie la PC en modo seguro hice escaneo con el nod 32 y detecto, desinfecto y elimino 5 trojanos. Luego hice correr el AVG Y el SpyBot ninguno de los dos detecto nada. Entonces prendi la pc como siempre y nuevamente hice esos tres pasos el AVG detecto:
