Salve, ho un grosso problema al pc, molto probabilmente è un virus. Oltre ad aprirmi pagine di publicità su ie (casinò ect) mi blocca anche l'aggiornamento di molti antivirus, solo avast riesce ad aggiornarsi. Ho fatto anche un scansione con spybot, ma non ho risolto il problema. Penso che sia qualche processo, vi riporto la scansione cn HijackThis. Ditemi se notate qualcosa di anormale, xkè io non me ne intendo xDDD

scarica Malwarebytes

http://www.malwarebytes.org/mbam/program/mbam-setup.exe




1) lo installi
2) lo aggiorni prima della scansione
3) fai una scansione scegliendo la modalità completa
4) NON eliminare le eventuali minacce che rileva
5) finita la scansione seleziona il tabellino log, apri il file di testo e postalo sul forum

Ah un altra cosa, il link per scaricare Malwarebytes non va, mi dice inesistente

Penso di si, ma ancora nn ho provato, che dovrei fare?

ok fatto, mi ha creato un file txt con scritto questo, ma il problema persiste. La cosa che mi fa preoccupare è che 3 giorni fa ho formattato per lo stesso identico problema, e ora mi capita di nuovo anche dopo una formattazione

scarica Avenger da qui

http://swandog46.geekstogo.com/avenger.zip

files to delete:
C:\WINDOWS\system32\msqpdxrerpjyxx.dll
C:\WINDOWS\system32\drivers\msqpdxlkdvgpjn.sys
C:\WINDOWS\system32\drivers\msqpdxmtetewnd.sys


Spunta "Automatically disable any rootkits found"

clicca sul pulsante "Execute"
Il pc dovrebbe riavviarsi da solo,se così non fosse riavvialo manualmente

posta il log di avenger che trovi in c:\




Analizza questo file in rosso su virustotal

http://www.virustotal.com/it/

C:\Documents and Settings\simon\Desktop\smss.rar
