Probleme de virus sur DD externe

Bonjour,
je vien vous demander un p'tit peu d'aide (aller beaucoup!! soyons fous!)

j'ai un probleme de virus qui se trouve sur mon disque dur extene.
Des que je l'allume tout se fige (internet antivirus souris) bref y'a rien qui marche!!!
des que je l'éteins rien ne change, je suis obligé d'éteindre mon PC directement a la tour

ma config avast home, windows xp sp2, amd 1.8ghz, 1go de ram

j'ai fais des scan avec spybot il ne m'as rien trouvé. Ad aware tourne au momen ou j'écris cette phrase. j'ai essayé de faire un scan des disques locaux avec avast mais il ne pren pas mon disque dur externe en compte car il n'est pas branché au momen ou je lui demande ( car sinon tout se bloque!!!) voila je vous poste mon rapport hijack

si quelqu'un as une solution n'hesitez pas!!!!
