trojan horse clicker.fnv

[lodicolo]

Salve a tutti, ho questo problema:
ho un pc con winxp ed ho installato avg free ultima versione il quale mi trova all'avvio del sistema un trojan horse clicker.fnv nella cartella ...temp\spoolsv32.exe. ho rimosso il file infetto e rifatto tutta la scansione anche in modalità provvisoria ma mi ricompare sempre. Ma non è solo questo il problema! All'avvio, oltre a trovarmi subito il virus il control center dell'AVG, mi si apre anche una piccola finestra che mi dice che a causa di un problema al services.exe il computer verrà arrestato e appare il conto alla rovescia di 60 sec. Qualcuno mi saprebbe aiutare? magari suggerendomi un sistema senza dover cancellare tutto?

Vi ringrazio tantissimo,

Monica

be inanzitutto ti consiglio di fare una scansione con hijackthis
vai qui e scaricalo
http://www.xnavigation.net/view/156/.../download.html
poi una volta che lai preso fai "do a system scan and save a logfile"
a questo punto copia il contenuto del log che ti è apparso e incollalo qui che lo analizziamo

ho salvato anche il file di log che mi ha dato systemscan però per me è sempre aramaico
potete scaricarlo qui:

che vuol dire "fixa"?
li devo cancellare con avenger?

e disattivare il system restore vuol dire disabilitare il ripristino configurazione di sistema?

forse è l' Obfuscated quello che si sostituisce ai file leggittimi rinominandoli in bak ?????

Edit: ho detto nà minchiata chiedo scusa

[Bugs Bunny]

disabilita il ripristino configurazione di sistema,
metti la spunta accanto a questo e clicca su fix checked:

O4 - HKLM\..\Policies\Explorer\Run: [5T19I3B27A] C:\WINDOWS\svchost.exe


poi in avenger immetti questo script:

Files to delete:
C:\WINDOWS\svchost.exe

poi fai una scansione con gmer e riporta le voci in rosso

il trojan sembrerebbe sparito o almeno gli antivirus non lo rivelano, l'unica cosa che continua ad apparire ogni tanto è questa finestrella:
