Malware recalcitrant

Bonjour,

J'ai toujours des boites de dialogues qui s'ouvrent me disant que rien ne va et qu'il faut que j'installe reparateurdesysteme ou defensedudisque ou antivirusordi enfin pleins de progs qui sont des rogues.
j'ai passé hijack dont le rapport suit mais dès que je "fix" la ligne en gras( qui, pour moi est le pb), ca fonctionne seulement pour 10 à 15 mn après c'est de nouveau pareil j'ai fait des recherches sur le net mais je ne trouve pas quel type de malware c'est. J'ai aussi passé spybot, avg antispyware j'ai avast en antivirus mais rien ne le détecte. Si je pouvais avoir un petit coup de main ca serait bien .

Merci et voici mon rapport Hijack:
