Virus qui se multiplie chaque minute (tmp)

Bonjour,

J'ai un petit probleme... Je me demandais pourquoi mon espace disque diminuait regulierement, et j'ai fini par trouver la source du probleme.
Dans mon dossier de messenger : C:\Program Files\Windows Live\Messenger se cree un fichier temp de 11,152KB toutes les minutes. Les fichiers se nomment RCX**** (ex : RCX1AE3.tmp).
C'est un leger probleme, puisque en 1h30 se cree 1Go sur mon HD (et comme mon ordi reste allume en moyenne 8h/jour...)

Heeeeeeeeelp!!! S'il-vous-plait!!

note : j'ai aussi un probleme de pop-ups depuis quelques temps. beaucoup de pop-ups s'ouvrent dans firefox (pourtant je n'autorise que dalle). ca peut aller jusqu'a 60 ou plus... c'est peut-etrealculez, lie, donc je fournie cette info au cas ou...

Merci!!

ci-joint le diagnostic :
