Pc infecté dont le systeme32 =(

Bonjour, Bonsoir,
J'ai du récupérer le pc d'un ami car mon ancien a rendu l'âme. Je suis dactylo et je travaille a domicile quasiment exclusivement sur mon PC. Il se trouve que le pc que j'ai récupéré est infesté de virus et trojan en tout genre.
Mon fiancé m'a conseillé de vous copier coller un rapport ce joint de hijack this pour vous faire gagner du temps.
