SVCHOST.EXE message d'erreur

Bonjour,
depuis quelque temps j'ai deux message d'erreur au démarrage de mon ordinateur:
1er:« windows ne trouve pas C:windows/svchost.exe vérifier que vous avez entré le nom correctement et essayez a nouveau»
2eme:«impossible de charger ou d'exécuter C:windows/svchost.exe spécifié dans le registre vérifiez qu'il existe ou supprimer la référence dans le registre»
J'ai vu sur cette page: https://www.sosordi.net/questions/136010/message-alerte-demarrage-de-mon-pc
que le problème pouvait être résolu grâce a un rapport hijack this, voici donc le mien:
