Aide pour un diagnostic PC (rapport Hijack)

Bonjour,

J'ai un ordinateur qui est assez lent (surtout au démarrage et fermeture), j'ai lancé une analyse antivirus Kaspersky, une analyse Malwarebytes et un ptit coup de Ccleaner, mais ça n'a pas donné de grande amélioration.

Voici mon rapport Hijack, si vous pouvez m'aider à l'analyser :)

Merci d'avance :
