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

timed.exe è un trojan, fixxalo

simonegabù

19-07-2006, 15:36

come si fixa?

simonegabù

19-07-2006, 15:37

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

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...
