Virus log hijack

bonjour, l'ordinateur de ma copine est infecté. Les premiers symptomes ont été une impossibilité de redémarrer l'ordinateur : Unmountable boot volume. Puis, après une réparation de windows avec le cd, j'ai lancé pas mal d'antimalware et antivirus.

Je poste ici les rapports...Depuis peu, F secure a échoué dans l'élimination du virus puis l'ordi a planté. Depuis, impossible de relancer Fsecure...

Voici les différents rapports : c'est un peu long, désolé. Si quelqu'un pouvait m'aider un peu, je suis une bille en informatique...merci.
