Virus isolé mais impossible à éradiquer!

Bonjour à tous,

Je crois avoir trouvé le responsable de mon ralentissement d'internet mais il m'est impossible de l'éradiquer!! En fait il s'agit de la ligne no 20 du rapport de hijack this. Si quelqu'un pouvait m'indiquer comment après avoir "fixer" cette ligne, je pourrais définitivement l'éliminer.
je vous fourni le rapport entier.
En vous remerciant.
