Trojan + W32/PariteB.....corriaces !

Bonjour,

Le pc de mon copain a contracté un trojan qu'antivir détecte avec les noms suivants :

tr/crypt.ULPM.gen
tr/rootkit.gen
tr/spy.gen
tr/BHO.eme
Trojan.Agent
tr/trash.gen

+Heur/Malware
+W32/Parite.B

Est-ce que c'est grave ?
La plupart sont dans systeme volume information.

Quelqu'un peut il m'aider ?

J'ai essayé Malware byte, ccleaner, et de les supprimer avec antivir mais sans résultat.
