Erreur registre + Fichiers POS.tmp

Bonjour,

Voilà depuis quelques jours j'ai des erreurs registe qui apparaissent au démarrage de l'ordinateur.
voila ce que ca me dit: " during a scan of files at system startup, potential errors in the system registry were found p-07-0100 IRQL: 1f sysver 0xff00024 KMODE_EXCEPTION_NOT_HANDLED" . Ensuite dans mes documents j'ai trouvé plus de 2000 fichiers POS.temps, j'ai tout formater et reinstaller windows hier je n'avais plus ce probleme et quand je me suis lever ce matin il est réapparu.
Voici mon rapport hijackthis
