[virus] Infecté par Trojan

Bonjour à tous,

je suis encore infectée par Trojan! Mon antivirus est bitdefender, dois-je en changer? Depuis que je l'ai installé, les virus s'enchaînent. Connaissez-vous un autre antivirus gratuit? Pour le reste j'ai Zone Alarm et Spybot.
Je vous envoie aussi mon rapport Hijack. Bitdefender m'a mis plein de trucs en quarantaine mais je ne sais pas si je peux les supprimer.

Merci d'avance!
