Problème avec l'utilitaire chkdsk

BONNE ANNEE A TOUT LE MONDE JE CHERCHE UNE SOLUTION POUR EXECUTER L'UTILITAIRE CHKDSK

Bonsoir
Lors de l'installation de windows live messenger, un message m'indique de vérifier mon disque avec l'utilitaire chkdsk.
Une bonne analyse anti-virus et anti-rootkit et anti-spyware sera la bienvenue je pense....

Merci de ta réponse rapide (je n'ai malheureusement pas pu rallumer mon ordinateur hier soir à cause d'un coupure de courant :@ ^^)
Je suis en train de faire une analyse antivirus avec Avira et je ne sais pas si ce logiciel fait également une analyse anti-spyware. Par contre pourrais-tu m'expliquer ce qu'est une analyse anti-rootkit? je ne suis pas très calé en informatique et ne connait que les bases (pardon si s'en est une ^^) Encore merci

Le scan de mon PC vient de se finir et voila le rapport : (désolé c'est un peu long :S)
