Problème VIRUS trojan MemScan ...

Bonjour,

Suite à un problème avec SOPROC.exe, j'ai fait une analyse avec Avast, puis Ccleaner et enfin BitDefender. Ils m'ont détecté un certain nombre de virus et je ne sais absolument pas comment m'en débarasser étant donné qu'en faisant une désinfection BitDefender me met échec de la Désinfection. Je vous mets ci dessous mes rapports et j'espère que l'on pourra m'aider.
