Ciao,
chiudi HijackThis in una cartella a lui dedicata (possibilmente non sul desktop), altrimenti perdi i backup;

<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> le seguente righe:

___________________________________________

svuota la cartella temp del tuo profilo:

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

svuota il cestino;

riavvia il computer normalmente.

fai qui un controllo antivirus qui;
http://security.symantec.com/sscv6/default.asp?productid=globalsites&langid=it&venid=sym

<b>Alla fine:</b>

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

Dovresti installare un firewall. Fai una ricerca su questo sito, hai solo l'imbarazzo della scelta

Grazie Pidue, ho risolto seguendo i tuoi consigli.
Ciao
