Blocage de certaines pages web

Bonsoir tout le monde,
Je viens de reformater ce week-end et je n'arrive plus à naviguer sur certaines pages web.
j'ai déjà eu ce soucis suite a un formatage. Il semblerait que cela vienne d'une mise a jour de sécurité windows qui bloque certains sites.
Je vous transmet mon rapport hijackthis en espérant un petit coup de main.
Merci pour votre aide si précieuse et longue vie au site.
Amitiés,

Apparemment ok.

• Télécharge Catchme (Gmer) sur ton Bureau.
• Double clique sur catchme.exe (le .exe n'est pas forcément visible) afin de le lancer.
• Lorsque la recherche sera terminée, poste le rapport catchme.log dans ta prochaine réponse.

Pas infecté pour moi.
