Bonjour,
j'ai cliqué sur un lien dans une fenêtre de conversation msn et d'un coup tout mes contacts l'ont reçu, les pages de conversation s'ouvrent seules et des pages mozilla et internet explorer aussi, j'ai scanné avec Ccleaner, spybot et malwarebytes, j'ai aussi lancé avast mais le pc est encore lent, de plus j'ai un icône en bas qui me dit "warning! security report Your computer is infected! It is recommanded to start spyware cleaner tool"
pouvez vous m'aider svp ?? merci d'avance

voici le rapport Hijackthis :
