Gràcias por la ayuda y perdonad per la tardanza en la respueta, queria que pasaran unos dias para asegurarme, parece que el problema esté por el momento soucionada.
Seguí vuestro consejos, pasando primero el vundofix, este no me encontró nada, supongo porqué habia pasado anteriormente varias veces, spyboot&destroy, spywareterminator, cccleaner i creo que algun otro.
Seguidamente le hice una limpieza con ccleaner y anti-malware, y estos tampoco encontraro nada relevante.
El problema parecia solucionado, pasé un dia y algo más probando, peró cuando le hice análisis con anti-malware me volvio a encontrar el vundo, el qual me eliminó y de momento no ha vuelto a aparecer, por ahora todos los anàlisis con la mayoria de software recomendades y otros me dan el sistema como límpio.
Cuelgo el ultimo reporte Hijackthis:

No me fio peró u permanezco en guardia, que programa me recomendais para proteger el pc? de momento uso el mcafee plus como antivirus, este peró en ningun momento me fue capaz de detectar nada, a más de que desde que lo instalé el ordenador va muy lento.

Tengo instalados todos los programa que he citado i de momento parece que filtran bien las entradas, ahoa bien no estoy seguro de si són los adecuados para la prevencion, por eso pido consejo al respecto.

En todos casos gràcias por la ayuda y pongo enfàsis sobre la utilidad de vuestros foros, dando las gracias por haberme ayudado y por todos los que cada dia sacais de problemas que muchas veces pueden ser serios.
