Aide, Analyse

Bonjour,

Alors voilà, j'ai un petit problème depuis quelques temps: je cherche désespérément comment optimiser mon ordinateur, je ne joue pas à des jeux excessivement lourds mais mon ordi rame à mort et je sais pas trop pourquoi...
-J'ai défragmenté mon disque dur aujourd'hui même
-J'ai téléchargé et fait une analyse avec Avira Antivir (version gratuite), CCleaner et Advanced System Care; et j'utilise Avast (version gratuite) depuis quelques années déjà...
-J'ai pas de programmes qui bouffent beaucoup de place

J'ai télécharger HiJackThis aujourd'hui et je voudrais savoir ce que vous pensez de ça:
