Hallo
ich habe das Problem, dass mein PC nach dem Start erstmal minutenlang arbeitet. Das dauert so ungefähr 6-10 min. Ich erkenne es daran, dass die HDD-Led ständig blinkt. Die Prozessorauslastung beträgt dabei 6-38%. Ich weiß nicht was ich tun kann, es sind auch nur wenige Programme im Autostart. Außerdem ist es auch nicht direkt nach dem Start sondern erst eine Minute später.
Hier mal mein Hijackthis-Log

Edit: Was ist hiermit ? Warum erstellst du ein neues Thema, wenn du bereits Hilfe von Cosinus hast?

Is aber ein anderes problem

Aber doch derselbe Rechner? Da reicht, was Malware angeht ein Thema.
