Ciao, fai così:
avvia il computer in modalità provvisoria;
rendi visibili le cartelle nascoste - da Risorse del computer >> Strumenti >> Opzioni cartella >> visualizzazione >> metti la spunta su:
"Visualizza file e cartelle nascoste";
toglila da "Nascondi file protetti del sistema (consigliato)"

Avvia hijackthis, con tutte le applicazioni chiuse,premi su <b>do a system scan only</b> , spunta ed elimina <b>(fix checked)</b> le voci che sotto ti elenco:
____________________________________________
<font color=red>
O4 - HKLM\..\Run: [ByteIdleLocksAxis] C:\Documents and Settings\All Users\Dati applicazioni\Hope Show Byte Idle\real bags.exe
O4 - HKCU\..\Run: [viewplus] C:\DOCUME~1\user\DATIAP~1\ERRORP~1\Base aim.exe
</font id=red>
____________________________________________

Con la funzione <b>cerca</b> trova ed elimina il seguente file in grassetto. Elimina anche la cartella che lo contiene;

C:\Documents and Settings\All Users\Dati applicazioni\Hope Show Byte Idle\<b>real bags.exe </b>;

elimina i file inutili con CCleaner, lo scarichi da qui (<b>N.B.</b>: in fase di installazione evita di installare la ToolBar Yahoo);
http://www.ccleaner.com/ccdownload.asp;

elimina le chiavi orfane di registro con RegSeeker. Lo scarichi da qui.
http://www.pc-facile.com/download/pulizia/regseeker/

fai una scansione on-line:
http://www.bitdefender.com

<b>Alla fine:</b>
rinascondi le cartelle di sistema;
rittiva il ripristino conf di sistema;
posta un log pulito.

<b>PS</b> Nel tuo pc manca un firewall. Se vuoi scarica da questo sito Zone Alarm e disattiva quello di Windows.
