probleme spyware type Trojan.Downloader.Inservice.JA

Bonjour !
j'ai un probleme avec des spywares : en effet lors d'un scan bitdefender il m'a trouvé plusieurs spyware type :
Trojan.Downloader.Inservice.JA,
Trojan.Downloader.Istbar.NN,
Trojan.Trembler.A,
et egalement Win32.Netsky.D@mm : je ne peux pas les supprimer ni desinfecter.
il trouve egalement le fichier wudupdate.exe dans \system32\ ... je suppose que je dois avoir d'autres trucs bizarres dans le genre ...
ci dessous le logfile de Hijackthis :

Salut
C'est pas des spywares que t'as choppé mais bel et bien des virus style chevaux de Troie
Tu devrais t'en tirer avec a2Free et surtout Kaspersky
