Topic: Aiuto non rieco ad eliminare un virus....

ho fatto tutto come mi avete detto. Volevo solo chiedervi come mai la scansione all'avvio di Avast non funziona più.

ho fatto la scansione in modalità provvisoria con tuttti i prog. :

Avast ha rilevato 2 files.dll infettati da Win32:Puper-E [Trj] e li ha cancellati mentre Microsoft AntiSpyware ha trovato Browser Hijack (BroWser Modifier). 

Ecco il log:
