Quelque chose ne va pas, mais quoi?

bonjour,

j'ai un problème et je ne sais pas si je l'ai résolu

donc après avoir attraper un virus (je suppose) qui me fait booter sur une recherche DHCP (l'allu quand même sur ce coup là) j'ai pu lancer mon xp normalement (ou presque) en débranchant le disque dur depuis lequel j'avais lancé l'installe d'une application téléchargée. c'est à l'issue de cette installation que les problèmes sont apparus.

donc voilà, je pensais que je n'aurais plus de soucis en débranchant ce disque
mais visiblement ça n'est pas terminé puisqu'après un reboot sauvage de mon ordi, mon pare-feu windows n'était plus activé
bon... je règle ce problème et je lance un scan hijackthis que voici
