éradiquer des virus trojan

Bonjour,
je suis très limité en informatique et n'arrive pas à ma débarasser de virus trojan depuis quelques temps. Cela ralentit considérablement la vitesse de mon PC.
Sur le forum j'ai suivi une manoeuvre d'éradication et me retrouve avec un rapport HijackThis que je ne comprends pas du tout.
Quelqu'un peut-il m'aider svp?
Voici le log
