Worm détecté par AVG iexp1ore.exe infecté

Bonjour à tous, AVG a détecté un "worm.agent.p" sur mon ordi dans les fichiers ie.exe et iexp1ore.exe. Lorsque je les mets en quarantaine, je ne peux plus ouvrir internet explorer sauf en allant dans l'arborescence trouver le vrai iexplore.exe. Voici un scan Hijackthis :
