Virus braviax

Bonjour,

Hier soir un cheval de troie a été détecté sur mon PC, et depuis j'ai une croix rouge dans la barre des taches me disant que mon pC est infecté.

De plus, une demande de connexion de braviax.exe à internet est apparue et j'ai cliqué sur refuser.
J'ai supprimé un fichier .dat qui était apparue sur mon bureau mais j'ai aussi remarqué qu'il y avait un fichier braviax.exe dans mon system32.

Voici le rapport hijackthis, que dois-je faire?

Merci.
