messages d'erreur au démarrage WXP - supprimer référence dsns le régistre

Bonjour, Après avoir installé et désinstallé plusieurs logiciels, mon pc met 5 minutes pour s'éteindre.
A l'allumage j'ai plusieurs messages qui indiquent qu'il est impossible de charger e.a. c:\program spécifié dans le régistre et me demandant de vérifier s'il existe ou de supprimer la référence dans le régistre. En cliquant plusieurs fois sur OK, Windows démarre mais reste lente.
Si un spécialist pourrait m'aider je serais heureux.
Je joins le fichier Hijackthis que je viens de faire
Merci
Jan
