Disattiva il ripristino di configurazione, leggi qui come fare
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=257&SH=N

Riavvia in modalità provvisoria, leggi qui come fare
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=344&SH=N

apri HIJAC THIS ed elimina come indicato in questo articolo
http://www.aiutamici.com/software/descrizione.asp?CodSw=1175
le righe che seguono.

Vai a PANNELLO DI CONTROLLO e clicca su OPZIONI INTERNET
nella finestra che si apre clicca i tre pulsanti
ELIMINA COOKIES - ELIMINA FILE - CANCELLA CRONOOLOGIA
poi clicca il pulsante PAGINA PREDEFINITA e su OK

al termine utilizza i programmi AD-AWARE e SPYBOT indicati in questo articolo
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=388&SH=N

sempre in modalità provvisoria fai una scansione Antivirus

quindi riavvia il computer e controlla se il problema e risolto, se e tutto OK riattiva il ripristino configurazione disattivato all'inizio di questa procedura e crea un nuovo punto di ripristino, leggi qui alla voce 8
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=170&SH=N

Fai una scansione antivirus on line da questo indirizzo
http://security.symantec.com/sscv6/default.asp?productid=globalsites&langid=it&venid=sym

Se la scansione on line rileva ancora dei virus, l'unica soluzione è formattare il disco fisso e reinstallare tutto

Se i file non si riescono ad eliminare in modalità provvisoria significa che il sistema è infetto e il virus protegge se stesso da cancellazioni, bisogna formattare e reinstallare tutto.
