Post hijackthis

voila je reposte le rapport de hijackthis pour plus de clareté:
tout d'abord il me semble que cela a commencé par winfixer qui ne cessait d'ouvrir des fenêtre pour me faire télécharger le logicile (ce que je n'ai pas fait)
puis tout un tas de pop up (searc-h, lottery pour la carte verte américaine....) et maintenant explorer.exe qui doit être fermé et qui me remet le message d'erreur dès que je ferme le précédent
ce que j'ai déjà fait:
