Analyse hijackthis?

Bonjour,

Mon pc est devenu lent alors j'ai utilisé CCleaner et Bitdefender . j'ai ensuite téléchargé hijackthis mais je ne comprend pas l'analyse et je ne veux rien effacer que je ne devrais pas .si quelqu'un peux jeter un coup d'oeil ca me renderais un fier service merci .

p.s. et si vous avez quelque conseilles pour mon pc trop lent ce serais apprécié :)
