comment enlever des faux antivirusRésolu/Fermé

Question

Bonjour, je vous explique mon problème : 
Cela fait quelque jours que des faux antivirus se sont installésq sur mon ordinateur, il y a :  Paladin
et un truc comme windows security ( je ne me rappelle plus trés bien le nom ). Je n'arrive pas a les supprimer de mon ordinateur. J'ai essayé beaucoup d'antivirus : avast, spy hunter, avira, spyware doctor . Mais soit l'an(tivirus ne le repère pas soit il me demande de le qsupprimer et des que je mets supprimer il revient 5 min aprés. Mon ordi recoit des messages toutes les 2 minutes disant qu'il y a des virus et u'il faut payer pour les enlever. J'aimerais bien savoir comment je pourrais les supprimer définitivement de mon ordi. Je fais donc appel a vos connaissances pour venir à mon aide. MERCI d'avance
