Plein de virus, help!

Bonjour,

j'ai remis en route mon ancien pc portable, un dell sous xp
il était et est toujours hyperlent
j'ai donc chargé malwarebytes anti malwares et fait un scan complet (près de 3 heures)
15 malwares
je suis pas sûr que tout soit supprimé
voici le rapport
merci de me donner une marche à suivre pour nettoyer ces saloperies
(j'ai fait passer ccleaner)
