Windows Security Alert

Bonjour,

J'ai un gros souci là...Une boite de dialogue Windows Security Alert s'affiche toujours toutes les 30 sec. Je me suis renseigné un peu partout et apparemment faut faire pas mal de vérifications intermédiaires.
J'ai passé un coup de Navilog et là plus de fenêtre. En revanche dès que je redémarre la machine, hop ça réapparait. Aussi, j'ai une tache en systray qui se lance de temps en temps me disant que je suis infecté de spywares. Firefox est aussi en rade du coup. J'ai lancé SmitfraudFix, CCleaner, AdAware aussi mais rien n'y fait.

Je vous indique ci-dessous un hijackthis après avoir passé le navilog :
