Spyware j'en peux plus!!!!

Bonjour,

Des que j'lance IE, j'ai des fenetres de telechargements de calendrier, d'horoscopes, des pages s'ouvrent sur lesquelles tente de s'installer trojan.downloader, enfin que du bonheur! Impossible d'éraqiquer le probleme malgré scan adaware, spybot et HijackThis! Ci-joint mon dernier log HijackThis ! En espérant qu'un expert puisse me rendre ma liberté..... D'avance merci.

Cordialement
Yoz.
