fai questo intanto che aspettiamo shapiro,tanto sono quasi certo che te lo consiglierebbe anche lui:
Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.aiutamici.com/software?id=80346
Prima di fare la scansione AGGIORNALO. (è molto importante)
Esegui una scansione completa del sistema.
se trova infezioni posta il log che ti rilascera'.
@shapiro:scusa l intromissione,solo che mi sembrava un po spaesato,spero che tu non te la prenda.

Scusa ma su Vista non c'è START - ESEGUI ! Non lo trovo. Poi volevo chiedere, dopo devo disattivare il mio antivirus e scaricare il vostro indicato ?
Il virus è stato eliminato, grazie a voi.

disattiva l'U.A.C.

qui e' descritto come disabilitarlo

esegui combofix col tasto destro e come amministratore, poi segui i passaggi che ti ha consigliato paolopa

NOTA:
Se postavi il log con la parte iniziale, dove e'descritto anche il S.O. ti avrei dato le indicazioni dall'inizio

arsenio26

devi postare il rapporto di combofix
