Alertes spyware permanentes

Bonjour,

J'ai été infecté par une charmante bestiole (il doit même y en avoir tout un nid !) qui m'alerte sur la présence de spywares sur mon ordinateur et voudrait bien me faire télécharger un anti-spyware.

Spybot m'indique la présence des pb suivants :
- 180 Solutions SearchAssistant
- 2020 Search
- SecondThought.STCLoader
- Zango
- SmitFraud-c
- SmitFraud-c.gp
- désactivation du gestionnaire de taches windows
Malheureusement, sitôt corrigés, les fichiers, clés de registres, etc. sont recréés automatiquement.

HijackThis me donne le log suivant :

Quelqu'un aurait-il un peu de temps pour m'aider à m'en sortir ?
Merci d'avance au GV (Gentil Volontaire) prêt à me donner un coup de main.
