Problème de redirection web, virus ?

Bonjour,

je crois avoir sensiblement le même problème que toi The n00b. Lorsque j'ouvre un résultat de recherche google, je suis redirigé une première fois vers yahoo ou un trucs de pop-up et si je reclic une seconde fois depuis google, j'atteinds enfin la bonne page.
En regardant mon gestionnaire des taches, et les processus ouverts, je suis tombé sur "unsecapp.exe", je l'ai fermé, et depuis, plus de problème. Seulement mon anti-virus (avast) ne le detecte pas comme vérolé et sur le net, je ne trouve rien à son sujet en tant que virus. De plus, sous vista, je n'arrive pas à le supprimer à cause des droits...

J'ai un fais un log hijackthis aussi j'espère que l'on pourra m'aider ...

Merci

Claire
