Hola Astareth, y de antemano muchas gracias por la ayuda. Lo primero es decirte que yo no he modificado el host ni puse la restriccion (al menos concientemente), segui los pasos pasa aque me indicaste, pero tuve problemas al descargar la herramienta hoster (la descarga y me salia que estaba malo el archivo) asi que la busque y la descarge desde aqui http://www.majorgeeks.com/Hoster_d4626.html , espero no haber cometido un error. Tambien elimine el flashget, pero no con el desintalador ya que no desintalaba el programa, asi que use la herramienta Killbox. Bueno hay me fui a modo seguro y segui los demas pasos, limpie temporales, cache, cookies, etc. y finalmente pase kaspersky al volver a el S.O. y me arrojo esto en el reporte:

PD: espero haber seguido los pasos bien y al perecer esta mas estable aunque como dije al comienzo a veces se demoraba hasta dos en caerse, lo de las transferencias aun sigue lento pero no siempre.
