Infection spyware, analyse hijackthis

Bonjour,

comme beaucoup de monde je suis envahi de spyware.
Je n'arrète pas d'avoir des fenêtre qui s 'ouvre dans firefox et qui m'envoi vers des site comme winantivirus pro 2006, security spyware ...
Pourtant j'ai zone alarm, kapersky, spybot et adaware, mais c'est passé quand meme.
voici mon hijackthis, si quelqu'un pouvait m'aider a le lire je l'en remercie.
