Ciao a tutti....ieri mi si è presentato il messaggio di errore con il file temp2.exe

Quindi sono venuto su questo forum ed ho letto che era un virus, quindi ho fatto scanione con avast (non lo avevo perchè ho istallato questa copia di xp solo per delle prove) all'avvio e mi ha cancellato alcuni file, fra cui c:\copy.exe, c:\host.exe, c:\window\scvhoste.exe ed altri....solo che ora, quando accendo il pc, mi compare un messaggio di errore che dice che non è stato trovato il file c:\window\scvhost.exe e poi un altro che mi dice di cancellare la voce di registro a cui è associato quel file....
Vorrei sapere se ho ancora tracce del trojan che dovrei avere tolto....io uso winzoz XP home originale aggiornato al SP3....ho fatto un log con hijackthis ed è uscito questo:

Ciao Er_Kratos,

1. Avvia il pc in modalità provvisoria
   
2. esegui hijackthis
   clicca su do a system scan only
   metti il segno di spunta a questa voce:
   

   Citazione:

   F3 - REG:win.ini: load=C:\WINDOWS\svchost.exe

   
   clicca fix checked
   
3. Riavvia il pc in modalità normale, rifai il log di hijackthis e postalo.
   
   
4. Disabilita il tuo antivirus
   
5. Collegati a BitDefender (con IE) e fai la scansione completa.
   
6. Collegati a Kaspersky on-line scanner e fai la scansione estesa, come indicato qui.
   Salva il risultato della scansione in un file (in formato TXT), carica il file su WikiSend e posta qui il Forum Link che ti viene assegnato.

Mentre davo un'occhiatina al registro di sistema ho cercato svchost.exe e mi ha trovato un file con indicato quel valore e l'ho cancellato. Ora sembrerebbe funzionare. In ogni caso ora provo a fare come mi hai detto....

[Er_Kratos]

Ecco il log....ora scansiono

Allora....bitdefender mi ha cancellato un file di istallazione di un programma (una banlist per un gioco) che sembrava essere innocuo....questo è il report con Kaspersky:

report.html

Dimmi se ho risolto così rincomincio a lavorarci....grassie

[bdoriano]

Allora... buon lavoro.

Se riscontri altri problemi, fai un fischio.
