Nombreux virus Aidez moi svp

Bonjour,
Mon antivirus bitdefender a mis en quarantaire Gen:Adware.Heur.irX@kGsgkKji.
J'ai téléchargé malwarebyte's selon certains conseils pour tenter de me débarasser de ce virus, et après une analyse rapide, c'est encore pire, il me trouve 15 éléments infectés.
Je vous en prie, aidez- moi, je suis novice.
Voici le rapport:
