Éléments infectés dans Malwarebytes

Bonjour membres du forum, j'ai aidé une amie qui avait des problèmes avec son portable en lui installant Malwarebytes. Son ordinateur avait des problèmes de lenteur et "gelait" souvent.
Voici le résultat de ce que le scan approfondie de Malwarebytes a donné que je joins à ce message. Pouvez-vous me dire si je peux détruire définitivement ces éléments en quarantaine? Ou en garder certains et les laisser dans la quarantaine? Je les laisse là pour le moment en attendant une réponse. Merci à l'avance...
