F2 - REG: system.ini: Shell = explorer.exe, killer.exe

Supprimer ce ^ ^. Il ya d'autres choses qui ont l'air étrange comme vous avez un trop grand nombre de cas de smss.exe marche.

F2 - REG: system.ini: Userinit = C: \ WINDOWS \ system32 \ userinit.exe

Aussi, je ne sais pas pourquoi userinit.exe, qui peut être un fichier légitime, est en system.ini

Supprimer killer.exe, puis de télécharger, mettre à jour et de lutte contre les logiciels malveillants d'exécuter malwarebytes.org
