TROJAN e svchost

[simonegabù]

Ciao a tutti, da un pò di tempo il pc che non formatto da un pò (circa 1 anno) ha iniziato a darmi qualche noia, tipo errori in explorer.exe ecc secondo me iniziati dopo aver installato msn live...boh..comunque, da un paio di giorni nod32 mi trova e cancella (più o meno quando sono su msn) questi file, che riconosce come trojandownloader.asune.J :
svchost.exe
se7vchost.exe
se9vchost.exe

sia nella cartella documenti sia in C:\Windows....
La cosa che non riesco a capire è che più o meno ogni volta che riavvio e vado su internet su siti affidabilissimi ma sono su msn il nod (AMON) li trova e li cancella..ho anche notato che il processo di windows svchost è presente parecchie volte nel task manager (adesso ce ne sono 7 di cui 4 in system, 2 servizi di rete e 1 servizio locale)...è normale???
E soprattutto, come faccio a liberarmene??vorrei capire da dove mi arrivano insomma..ho provato anche hijackthis ma non mi segnala niente di pericoloso...vi sarei grato se riusciste a darmi una mano...
Ciao a tutti!

fai la scansione con questo removal tool:

e fai windows update, poi posta log hijackthis, può essere normale che svchost sia ripetuto, assicurati che msn live sia l'ultima versione

Allora, ho fatto lo scan con il programma che avete postato sopra ma non trova nulla, a questo punto vi allego il log di hijackthis

Uno dei servizi che non so cosa siano è timed.exe e neanche hijackthis mi sa dire niente al riguardo...

timed.exe è un trojan, fixxalo

[simonegabù]

come si fixa?

[simonegabù]

e sndman.exe?che mi dite?

e sndman.exe?che mi dite?

Dovrebbe essere un trojan, sono praticamente sicuro, tu per sicurezza analizza il file su questo link: virusscan.jotti.org poi se ti dovesse dare la conferma fixa anche questo. Per fixxare basta che lo spunti, fai do a system scan poi una volta fatto accanto alle voci che desideri eliminare le spunti e poi fai fix checked

[simonegabù]

ok, avevo trovato come fixare, però non riesco a trovare il file sndman.exe in nessuna cartella, solo un file in prefetch ma non è un applicazione...intanto non riesco a rimuovere definitivamente i secvhost e compagnia bella che ad ogni riavvio mi vengono nuovamente identificati e cancellati da nod..resto ancora perplesso dai vari svchost.exe, magari è normale che ne vengano lanciati anche 7 contemporaneamente...
