Log hijackthis, spyware ou malware ?

Bonjour, je viens de formater mon ordinateur il y a de cela 3 semaines et j'ai à nouveau un problème de navigation internet dû probablement à un spyware ou à un malware qui me redirige toujours sur une autre page.

Est-ce que quelqu'un pourrait m'aider svp!! J'ai décidément besoin de ma partition windows.

Merci beaucoup à l'avance
Isabelle
