Erreur service

Bonjour,
Depuis 4 jours j'ai toujours ce message quand ja'llume mon PC : "services.exe a rencontré un problème et doit fermer.", et après la machine se redemarre toujours.
J'ai vu sur un forum de scanner la machine avec hijackthis et j'ai aussi lancé diaghelp et lors du scan j'ai vu ce message

Recherche de rootkit! (Merci S!Ri)
C:\WINDOWS\system32\drivers\orean32.sys existe !

Windows m'affiche aussi le message d'erreur comme EXPLORER.EXE ...

A part ça la mise à jour automatique de mon antivirus "Antivir" a toujours un problème en m'affichant le message "internet connexion failed"
Que dois-je faire
Comptant sur votre compréhension et votre aide

Voici le rapport hijackthis :
