Trojaner-Board - PC schaltet sich selbstständig aus!

Tag liebe community!

Seit einigen tagen plagt mich ein problem, und zwar fährt mein pc in unregelmäßigen abständen einfach runter (plop, schwarzer bildschirm - PC aus). mal sofort nach einem neustart, ein anderesmal erst nach 1-2 stunden. habe antivir etc durchlaufen lassen der hat jedoch nichts gefunden.

habe schon google durchsucht und zu 90% wird gesagt es liegt an einem virus.
hab bereits befehle wie "shutdown -a" ausprobiert helfen jedoch nicht.

hier mal mein hijackthislog.
