Alerte! Cheval de troie: dropper.generic.drwz

Bonjour,

J'ai attrapé un virus cheval de troie: dropper.generic.drwz. J'utilise window xp et l'anti virus AVG. J'ai fait quelques recherche et donc, j'ai fait une analyse avec hijackthis.

Merci de m'aider à me débarrasser de ce virus.

Voici le rapport Hijackthis:
