Probleme pointeur souris et memoire vive

Bonjour,

depuis ce matin je remarque que mon pointeur souris a du mal de temps en temps (son apparence change aussi) sur le net et que ma mémoire "ram" est bien alourdie par rapport à d'habitude
j'ai effectué un scann malwarebytes et antivirus mais rien, ils n'ont rien detecté
je post le rapport hijackthis si quelqu'un y voit quelque chose je l'en remercie d'avance pour l'aide
