Analyse HiJackThis après Worm.Win32.Otwycal.c

Bonjour,
Après un simple scan, A² m'a trouver un worm dans mon processus explorer.exe (Worm.Win32.Otwycal.c) , après avoir galéré pour le virer de là (Plusieur Scan et suppresision inutile, Mise en quarantaine d'Explorer, ReScan et suppression, Supression d'Explorer.exe @_@), je me suis lancé donc danc une vérification de mon PC pour voir s'il n'yavait pas d'autre probleme suite a ça.
A-squared, Avast, Spybot, Ccleaner y sont passés, et maintenant HiJackThis
N'étant pas un as en informatique (loin de là ^^) j'aurai besoin d'une petite analyse HiJackThis si possible
Merci ^^
