Bug windows

Bonjour,

voila j'ai un bug depuis quelques temps enfaite au bout d'un certains temps quant l'ordinateur est allumé, internet ne marche plu et tout les autres programme qui sont ouvert ne reponde plu et quant je veut ouvrir n'importe quel programmes le message suivant aparait:
"windows ne parvient pas a accéder au périphérique,au chemin d'accès ou au fichier spécifier.vous ne disposer peut etre pas des autorisation appropriées pour avoir accés a l'élement"
sa me bloque tout mon ordi donc jaimerai savoir que quoi cela vient :virus,probleme base de registre...
j'ai fait une analyse avec hijackthis pour savoir si sa vient da sa et voici le rapport:
