Hijackthis

Bonjour à tous,

J'ai depuis plusieurs mois de gros soucis avec mon ordinateur, il s'est mis sérieusement à ralentir lorsque je surfe sur internet, que je consulte mes mails ou encore que je regarde des vidéos sur Youtube. J'ai téléchargé HiJackThis comme on me l'a conseillé sur un autre forum mais une fois que j'ai réalisé un scan je suis complètement perdu et je n'ai aucune idée de ce qu'il faut faire pour redonner une santé à mon ordinateur. Si vous pouviez m'aider...Merci encore du temps que vous m'accorderez. Amicalement.

P.S: je vous met ci dessous le scan réalisé
