Buona sera dopo aver utilizzato ogni tipo di antivirus senza riuscirne a trovare uno che risolvesse il mio problema sono arrivato su questo forum...
Il mio problema è che iexplorer.exe fa aprire pagine(in background quindi non visibili) che bloccano il proxy(probabilmente modificano le impostazioni)...gli url di queste pagine sono scritti nel file txt hosts e la rimozione è impossibile(anche con HijackThis) infatti compare il messaggio d'errore "accesso negato"...c'è qualcuno che puo aiutarmi a risolvere?...grazie mille

eseguito alla lettera ma niente...continua a connettersi agli host(01- Hosts:)...grazie mille comunque per la risposta....ps:la ddl si è tolta gli url no....

gia fatto...come scritto nel titolo accesso negato :)....anche con il programma è uguale...continua a rimanere quella lista in fondo all hosts.txt

bravo il problema è proprio questo....anche eliminando il file host,ne esiste un altro(quello infetto) che è invisibile nella cartella etc(solo con hijacthis si riesce a vedere proprio con host manager)

il problema è che da quando apro Hijackthis mi avvisa da subito che il file host è denied...mi sa che rimane solo andare in assistenza...

Se proprio devi andare in assistenza...in questi casi una formattata non sarebbe male.
