Win:trojean-gen et adware .gen help !

Bonsoir, mes chers enfants n'ont pas géré l'intrusion des virus. Quelle bonne surprise au début des vacances. Comme c'est la première fois, j'ai vraiment besoin d'aide. Il s'agit de trojean-gen arrivé hier (6 fichiers mis en quarantaine par avast) et de adware gen (2 fichiers).
Je suis sous XP SP2 avec internet explorer 7. J'ai AVAST et A squared free c'est tout et j'ai voulu installer KERIO mais il empêchait la connection avec le réseau local et je ne savais pas comment faire alors je l'ai désinstallé. J'envoie un log HijackThis et j'espère que quelqu'un va venir à mon secours avant bientôt !!!
