C:\Windows\VM305_STI.exe

Bonjour,

Depuis plusieurs jours l'écran de mon PC s'éteint tout seul au bout d'un certain temps. Il affiche ensuite "pas de signal" alors que la tour est toujours allumée.
Je l'ai nettoyé, j'ai vérifié les cables.
J'ai fait une analyse Avast au démarrage qui a trouvé que ce fichier était infecté : C:\Windows\VM305_STI.exe.
N'arrivant pas à le supprimer avec ce logiciel, j'ai essayé de faire un Malwarebytes mais l'écran s'est éteint au milieu de l'analyse...
J'ai donc essayé de le supprimer manuellement mais rien n'y fait, l'écran s'éteint toujours...

Voici l'analyse Hijackthis que je viens de faire :
