Ordinateur lent

Bonjour,
Mon ordinateur est très lent depuis quelques temps. Je travaille avec cet ordi alors j'ai besoin qu'il soit à son plein potentiel. J'ai Symantec comme firewall et anti-virus. J'ai vu qu'il y avait quelqu'un qui avait le même problème que moi et il lui avait été conseillé de faire un scan avec Hijackthis et MalwareBytes, alors j'ai fait la même chose. Je poste les rapports ici.

Merci beaucoup d'avance et bonne année!
