Interpretation hijackthis

bonjour,

j'ai fait analyser avec hijackthis le pc d'un ami mais je ne sais pas l'interpreter, je ne suis pas specialiste info mais plutot reseau, donc je fais appel a vous les specialistes. La personne avait norton qu'il a desinstallé, le malware qui s'execute sur le pc s'appel spyware figther.
Il se lance automatiquement avec le double clique sur un programme et lance une fenetre windows lui demandant de s'installer.
Je lui ai fait telecharger adware, spybot et fait faire un scan avec kapersky. J'ai tenté avec msconfig mais tjs rien .
J'aimerai eviter le formatage du pc, merci 'avance pour vos reponses, conseils et votre temps.

Voici le log :
