Analyse log Hijackthis,merci

Bonjour,

J'ai le log Hijackthis d'un ami,est ce que vous pourriez l'analyser?En fait il y a des fenêtres de pub qui apparaissent et je ne sais si c'est lié a une infection mais Antivir a du mal a s'installer(il n'avait pas d'antivirus avant...) et Windows SP2 indique qu'aucun antivirus est installé...

Je pense qu'il faudrait utiliser le logiciel navilog1 pour les problèmes de pub,qu'en pensez vous???
