SALVE,
ogni volta che mi connetto mi appare un messaggio di virus (antivirus avast),
provvedo a cancellare ma mi riappare in continuazione con nomi diversi vedi lista:
C:\WINDOWS\system32\ritmvFF.dll
C:\WINDOWS\system32\fJluJCV.dll
C:\WINDOWS\system32\wTdqOkOY.dll
C:\WINDOWS\system32\HYGvrRNoVrd.dll
C:\WINDOWS\system32\LOOEwwstUwQ.dll
C:\WINDOWS\system32\RNhCjRkjW.dll
C:\WINDOWS\system32\MyonmVWUaq.dll

Ho provato a fare la scansione anche in modalità provvisoria e sia con l'antivirus che con spyboot e lavasoft, ma il problema persiste.
Potete aiutarmi?
grazie luciano

Ciao Luciano, prova a fare una scansione antivirus online, ad esempio qui:


http://www.pandasoftware.com/activescan/it/activescan_principal.htm

clicca sull'immagine dove c'e scritto PandaActiveScan e poi segui le isrizioni che ti da il sito.

ciao

ciao alfonso,
ho provato a eseguire tutti i passi indicati senza risolvere il problema.
Di seguito vi allego il log :
grazie luciano

Salve alfonso,
ho provato ad eseguire quanto mi hai desritto
ma purtroppo avast continua a darmi, solo quando sono connesso, messaggio di file infetto da virus. ma non riesce ad eliminarlo.
Ti mando il Log di avast per vedere se puoi aiutarmi.
Grazie Luciano
