Merci.

Les messages "(file missing)" sont peut-être dus aux messages "Unknown owner".
 
Les messages "Unknown owner" sont nombreux et anormaux.

Oki donc que faire ?
Supprimer ces services ?

Je noterais le nom des services. Je les arrêterais et demanderais qu'ils ne soient pas lancés automatiquement dans le gestionnaire des services. Je repasserais un hijackthis qui ne devrait plus les montrer. Je testerais si ça marche mieux.
