grazie per la vostra cortesia

Il log se lo posti in virus sicurezza e privacy hai maggiore possibilità che sia letto.Io non sono un grande esperto di Hijack ma mi sembra che tu abbia attivo il Tea Timer di Spyboot questo puo causare qualche inconveniente per disattivarlo apri Spyboot clicca su Modalità e scegli Modalità avanzata quindi Utilità\Resident.Nella finestra togli la spunta a Attiva il modulo Tea Timer.
Prova a dare un indirizzo fisso alla connessione invece che automatico.
