Internetstartseite bei Neustart immer verändert

Hallo
Meine Internetstartseite und meine Favoriten werden nach jedem Start von irgendeinem Programm umbenannt. Mal WWW.---woods.com oder C:\WINDOWS\_h.html. Wer kann mir helfen? Habe jetzt schon mal 2 verschiedene Virenscanner F-secure, antivir und adaware drüberlaufen lassen, Keine Angaben von den Programmen zu meinem Problem.
Hier nun mein Hijack logfile:
