Virus Trojan generic impossible à éliminer

Bonjour,

Le scan antivirus approfondi de Bitdefender (version d'évaluation) détecte un virus Trojan generic sur mon ordi qui infecte 18 fichiers sous C:/windows... restore...etc. Bitdefender ne peut nettoyer ces fichiers car le virus (ou les fichiers) fait partie d'une archive (c'est ce qu'il précise dans le rapport du scan). Idem pour avast family 4.8.

ordi risque-t-il quelque chose ? Que puis-je faire pour éliminer ces fichiers infectés ?
Bitdefender dit qu'il a bloqué ces virus et que l'ordi n'est affecté par aucun problème. Malgré tout, j'aimerais en savoir plus.
J'ai aussi fait un scan hitjack this que m'ont conseillé de faire deux personnes qui m'ont répondu sur ce forum dimanche dernier.

Le voici. Que doisfaire de plus ?

Mon ordi : windows XP Internet explorer
Il fait beaucoup d'erreurs et est très lent
