Encore à propos du trojan Vundo

Bonjour,

je suis une petite débutante dans l'informatique et bien que j'ai lu avec attention tous vos messages à propos de la détection et l'éradication de ce trojan, il est encore présent dans mon ordi. Je vous explique la situation: antivir me détecte Vundo sous ces noms là: TR/Vundo.AG ou TR/Vundo.Gen ou TR/Dldr.WMA.Wimad.N. Spybot, A-squared Ad-aware et AVG ne me le détectait pas au début. Quelques jours après, Spybot m'a detecté Virtumonde. Il me l'enlevait, le trouvait ... (J'ai appris plus tard que Virtumonde est l'autre nom de Vundo. ) Mais les autres logiciels de protection ne me détectaient rien. J'ai alors téléchargé des anti-trojan comme Trojan remover, Fixvundo, ou un anti-virus qui s'appelle Multicleaner, bref aucune détection non plus ou alors s'ils détectaient quelque chose, ils l'effaçait et me disait qu'il n'y avait pus rien. Je redémarre l'ordi, je refais des scan, rien n'est détecté mais j'ai toujours Antivir qui m'informe qu'il y a un un trojan. Comment faire merci?

Je conseille de renomer Hijackthis, pour contrer une éventuelle infection de Vundo.

ex:Renomme le fichier HijackThis.exe en eden.exe pour cela, fais un clic droit sur le fichier HijackThis.exe et choisis renommer dans la liste

Ensuite avec Explorer créer un dossier c:\hijackthis
Décompresser Hijackthis dans ce dossier.
C'est important pour les sauvegardes."

Je suis désolée mais tu peux expliquer plus clairement parce que là je vois pas du tout comment faire ... je n'y connais vraiment rien et le peu que je sache c'est grâce à mon copain qui d'habitude s'occupe de mon ordi.
