Problème de cmd.exe

Bonjour,

J'ai eu un problème avec le cmd quand je tape "command" dans exécuter ça me dis :

C:\WINDOWS\system32\command.pif
Répertoire de démarrage non valide, vérifiez votre fichier PIF. Choisissez 'fermer' pour mettre fin à l'application.

Alors voici le rapport hyjackthis que j'ai obtenu et j'espère que vous allez m'aider a résoudre ce problème !
