Ciao fragus,
esegui queste operazioni

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

2) 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
