Problème Trojan

Bonjour,

J'ai eu récemment une attaque de trojan. Je n'arrivais plus à accéder à Windows Seven. Ne m'y connaissant pas trop, j'ai demandé à un ami de m'aider. Il m'a conseillé de télécharger Malware Bytes et de l'exécuter en mode sans échec. J'ai supprimé tout ce qui a été trouvé. Windows redémarre normalement maintenant, seulement voilà, chaque 5 secondes, j'ai une fenêtre d'erreur "Windows Explorer a cessé de fonctionner qui apparait" et je dois cliquer dessus pour que mes fenêtres disparaissent et réapparaissent.
L'ami en question m'a dit de télécharger Hijackthis et d'analyser avec mon PC et de poster le résultat ici pour que des âmes généreuses puissent m'aider à résoudre mon problème.

Voilà le fichier:
