Analyse du log hijackthis

Bonjour !
Avant de vous appeler au secours, j'ai essayé des tas de choses.
Malheureusement, rien n'y fait et mon PC est toujours envahi par les publicités et maintenant, il se coupe même tout seul.
Mc Afee m'indique Look2Me
Cwshredder ne trouve rien
spybot me trouve hotsearchbar.
Je vous joint le log hijackthis, si vous vouliez bien me dire ce qui ne va pas, ce serait gentil.
Merci.
