Analyse du log Hijackthis de mon pc

Bonjours a tous !
J'en appelle a votre sagesse. Mon PC est, a mon avis, très sale et engorgé. A ce que j'ai lu, je ne me trompe pas et dans une autre page de CCM, on recommande de soumettre le rapport de Hijackthis ici. Je ne m'essayerais pas seul de le désinfecter car la dernière fois que je me suis aventurer dans les méandres de mon pc, ca m'a couté 56 $ CAN...

Merci de me filler un coup de main. Je suis conscient que je ne suis pas le seul a vous implorer lol
