Re-bonjour, j'ai essayé de bien suivre tes instructions. Pas mal de problèmes semblent résolus. Je n'ai pas réussi à supprimer C:\WINDOWS\SYSTEM32\drct16.dll. D'autre part, le fon d'écran de mon bureau Windows reste bleu marine avec au centre un cadre noir avec le message suivant : « WINDOWS ERROR System has detectedspyware activity. Some system functions are blocked out. Windows recommand you to clean your PC with a spyware removal tool. This has to be done as soon as possible to prevent loss of data.”
J'ai toujours des fenêtre “Aurora” avec des pubs qui s'ouvrent dans IE.

Voilà le scan AV et un nouveau rapport hijackthis !
