HijackThis-Logfile brauche Hilfe

ignition

Hallo! Seit längerem werde ich von Werbeseiten genervt, die sich einfach selber öffnen. A-Aware findet die verantwortliche Datei, diese generiert sich aber immer wieder.
Auch eine Installation vom XP-Servicepack 2 hat nicht geholfen.
Kennt jemand eine Lösung oder komme ich nicht mehr ans Formatieren vorbei (Das wäre nämlich ganz mies)?
Hier das Logfile:
