Ciao, scarica <b>VirIt</b>, installalo, aggiornalo e fai un paio di scansioni in modalità provisoria. Potrebbe bastare.

http://www.tgsoft.it/files/vnlt6157.exe

Poi <b>Disattiva il Ripristino configurazione di Sistema</b>: ------ > <b>procedura:</b>

<b>avvia in modalità provvisoria</b> ----- > <b>procedura:</b>

<b>rendi visibili le cartelle nascoste</b> ------ > <b>procedura</b>:
da Risorse del computer:
Strumenti >> Opzioni cartella >> visualizzazione;
metti la spunta su:
<i>Visualizza file e cartelle nascoste</i>;
togli la spunta da:
<i>Nascondi file protetti del sistema(consigliato)</i>


Avvia hijackthis, con tutte le applicazioni chiuse, premi su <b>Do a system scan only</b> , spunta ed elimina <b>(fix checked)</b> la seguente riga:

---

<font color=red>R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = file:///C:/bookmark2.htm
</font id=red>

---

Vai su Strumenti >> Opzioni Internet, elimina la cronologia, i files temporanei internet, i cookies;

svuota il cestino;

riavvia il computer normalmente.

<b>Alla fine:</b>

rinascondi le cartelle di sistema;
riattiva il ripristino configurazione di sistema e, se tutto è a posto, creane uno nuovo.

Nel tuo sistema manca un firewall.In quesro sito trovi Zone Alarm.
