Esegui systemscan, clicca sul pulsante "Removal Script" e, nella finestra che si apre, copia/incolla questo script:

HKLM\system\controlset001\enum\root\legacy_gxvxcse rv.sys
HKLM\system\controlset002\enum\root\legacy_gxvxcse rv.sys

Clicca su "Proceed with removal" e il pc si riavviera' per eseguire lo script.
Al riavvio troveri la finestra di SystemScan con un messaggio (blu se lo script e' stato eseguito correttamente - rossa in caso contrario): controlla l'esito e rieseguilo se necessario.


analizza su Virustotal il file C:\Documents and Settings\Francisco G\Impostazioni Locali\Temp\RtkBtMnt.exe e posta il link dell'analisi.

carica anche un nuovo rapporto di systemscan.

ho già fatto quello che mi hai detto, e il system scan removal script è a posto.

cuando ho riavviato il computer, mi è uscita una finestra di Avira dicendo que ha trovato il malware in C:\Avenger\gxvxcbossqtoijwqxryrotepadbdwkrjipttiv. sys, the TR/Agent2.iex.

questo è l'analisi di virustotal

allora.. avenger è il tool integrato in systemscan, quello che hai in pratica usato per eseguire la rimozione.

riguardo il file sys che sta nella cartella avenger, avira ora te lo trova, si.. , ma il file è stato in effetti eliminato.. quello che vede è solo il backup perchè non è piu' attivo (prima lo era e non lo vedeva..)

finiamo di eliminare dei file che non servono.. riesegui systemscan con questo script pero' cortesemente disabilita avira prima di eseguirlo (ovviamente anche disconnesso da internet) e ricordati di riattivarlo non appena il pc si è riavviato:

files to delete:
C:\WINDOWS\system32\gxvxccounter
C:\zip.exe
C:\l^cmpvyr.bat
C:\avexport.bat
C:\WINDOWS\system32\drivers\riwfdjhy.sys

registry values to delete:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run | dfgylebw

riattiva l'anivirus..

vedi come va il pc.
se è tutto ok, puoi eliminare la cartella c:\avenger e systemscan, che non servono piu'.

ciao

[panchogianza]

Grazie mille per l'aiuto, tutto sembra ok adesso. Ho eseguito BitDefender, e Kapersky online scanner sensa nessun problema. Prima non poteba farlo.

ciao!

[Deifobe]

ok ..
