Souci avec mon pc

Bonjour a tous,

Mon PC est devenu de plus en plus très lent....
J’ai essayée le nettoyage mais aucune amélioration n’est constatée. Je pense que j suis infecté par un virus et je voudrais le supprimer sans formater mon pc .

J’aimerais avoir SVP votre aide en vérifiant si c'est bon ou pas !!

Merci d'avance
