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

<b>disattiva il ripristino configurazione del sistema in questo modo</b>:
tasto destro sull’icona Risorse del computer >> Proprietà >> Ripristino configurazione di sistema: togli la spunta dal quadratino dove c’è scritto :
<i>disattiva ripristino configurazione di sistema su tutte le unità</i>;

<b>avvia il computer in modalità provvisoria in questo modo</b>:
riavvia il computer e appena acceso, quando vedi le scritte bianche che appaiono velocemente sullo schermo nero premi ripetutamente il tasto F8;

<b>rendi visibili le cartelle nascoste in questo modo</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>

Vai nel pannello di controllo e disinstalla quello che non hai installato tu.

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