Demande aide pour lecture rapport Hijackthis

Bonjour,

Y a t-ii une âme charitable pour interpréter le rapport Hijackthis de mon PC ci-dessous.
J'ai un problème au démarrage, un message informe d'un problème avec le fichier: NA_service.exe et j'ai également un problème d'instabilité dont j'ignore l'origine !!!!!
Merci pour votre aide par avance.
