Mein Internet Explorer öffnet sich ständig- suche gut durchführbare Lösung

bser

Hallo!

Seit kurzem öffnet sich bei mir der Internet Explorer ständig mit Werbeinhalten, obwohl ich Firefox benutze.
Das habe ich gegoogelt und bin auf dieses Forum gestoßen.
Ich bin sogleich den hier beschriebenen Angaben gefolgt, HiJack von ChipOnline runtergeladen und eine Analyse gestartet. Hier das Logfile:
