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)
