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/hijackthis/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

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

poi in avenger immetti questo script:

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:
