Ciao mauriziocv .
Qualcosina c'è da eliminare.
Assicurati di avere accesso a file e cartelle nascosti
(Pannello di controllo-> Opzioni Cartella-> Visualizzazione)
1) Metti la spunta su: Visualizza file e cartelle nascoste
2) Togli la spunta: nascondi file protetti di sistema

Disattiva il ripristino configurazione di sistema, e tienilo disattivato, fino alla soluzione del problema http://guide.aiutamici.com/guide?C1=7&C2=68&ID=80121

Se non sai "fixare"le voci,segui questa guida dettagliata: http://www.aiutaamici.com/software?ID=11175

Avvia in modalità provvisoria http://guide.aiutamici.com/guide?C1=7&C2=68&ID=80122

Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su fix checked

Trova e cancella i file in rosso:
C:\documents and settings\pc\impostazioni locali\dati applicazioni\qscfq.exe

Scarica VIRIT :
http://www.tgsoft.it/italy/download.htm lo aggiorni (cliccando sulla parabola in alto) e lo fai girare in Modalità Provvisoria (è molto importante).

Scarica Spy-Bot da qui http://www.aiutaamici.com/software?ID=10831 e fai una scansione sempre in Modalità Provvisoria.

Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223

Riavvia il computer.

Fai una scansione on-line con questo http://housecall.trendmicro.com/it/
Ricordati di rinascondere le cartelle di sistema;
Riattiva il ripristino configurazione di sistema e, se tutto è a posto, creane uno nuovo.
