PC infecté par TROJAN-DOWNLOADER.WIN 32.SMALL

Bonjour,

Mon Pc est actuellement infecté par 2 trojan-downloader.win 32.small.tnt. J'ai découvert celà en effectuant un scan en ligne via mon fournisseur d'accès Orange.
Les 2 fichiers infectés sont:
C:\Documents and Setting\ROCHETTE\Local Setting\Temporary Internet Files\content.IE5\6G8 TD PRJ\wv [1].exe

C:\WINDOWS\System32\svlzkk.exe

Je suis sous Windows XP pack2 avec Mac Afee comme antivirus et parefeu (le parefeu windows étant désactivé).
A noter que mon anti virus n'a pas détecté ces 2 infections.
En lisant des posts sur ce trojan, j'ai effectué un scan avec hijackthis. Voici le rapport ci après pour vous apporter les informatins nécessaires.
Je suis novice dans ce domaine, alors je fais appel à une ame charitable qui voudra bien me porter secours.
Merci d'avance.
