Programmes qui ne répondent plus

Bonjour,

Cela fait maintenant 2 semaines que certains programmes de mon ordinateur ne répondent plus, et cela arrive aléatoirement. Par exemple, mon navigateur internet ne répond plus d'un coup sans raison apparente.
J'ai donc fais une analyse avec malwarebytes anti malware et mon antivirus, et ils n'ont pas trouvé de virus.
Finalement, j'ai fais un scan avec Hijacthis et voici ce qu'il me donne :
