CPU nach 20 min --> 100% ausgelastet

Xare

Hi, habe folgendes Problem:
Nach dem Einschalten meines Laptops, läuft alles wunderbar, doch nach 20 Minuten ist auf einmal die CPU zu 100% ausgelastet! Hab nun schon sämtliche Programme aus dem Autostart entfernt. Ebenso meine Anti-Vir software kaspersky besser eingestellt:
Habe bereits CCleaner und Anti-Malware laufen lassen...

Hier noch das HijackThis-Log-File, hab es auch schon automatisch auswerten lassen- keine Auffälligkeit:
