Bonjour , 
Pourrais tu donner ta configuration (os , mémoire ; carte graphique, disque dur) ?
Est ce que tu a fait un scan avec avast ? 
A quand remonte ta dernière defragmentation ? 
Est ce que le pc est lent depuis l'installation d'un logiciel ?

Essaye de faire un peu de nettoyage avec Ccleaner .

Bonjour et merci de répondre aussi rapidement.

Alors tout d'abord voici ma config' : Windows7 64 bits, Intel core i5CPU650, 4 GB RAM et avec une carte AMD Radeon HD 6800. Le pc est récent (deux mois) et je n'ai donc pas eu l'occasion de faire de défragmentation. Avast, Malwarebytes antimalware et AVPtoll n'ont rien détectés donc c'est rassurant... J'utilise aussi ccleaner régulièrement.
