Spyaxe encore et toujours...

Bonjour a tous,
je suis en galere avec spyaxe et son pote spytrooper, ainsi qu'avec w32.sinnaka. Comment faire pour les enlever ? ma page d'acceuil change et je ne peux pas la modifier et j'ai en permanence l'info "your computer is infected". J'ai navigué sur le forum et voici le log hijack. Si qq peux m'aider avant que je craque pour le format...
