Rapport Malwarebytes'

Bonjour,

Ayant lancé Malwarebytes' afin de détecter d'éventuels problèmes, le rapport m'indique plusieurs infections. Pouvez-vous m'indiquer les démarches à suivre pour supprimer ces infections?
Je précise que le scan de mon antivirus ainsi que spybot n'ont rien détecté.
Merci par avance.

Voici le rapport malwarebytes':
