Salve ragazzi! Ho un bel problemino da circa due settimane ho riscontrato che quando utilizzavo internet explorer per le ricerche al mio cliccare sul link mi reindirizzava in una pagina 66.etc.etc in pratica non sicura..allora ho eliminato explorer e ho installato firefox ma il trojan così descritto dai vari antivirus da me utilizzati è rimasto..e sembra essere una chiave di registro dll che non si riesce a cancellare neanche con hijack perchè (come dice quest'ultimo) essere un file di sistema(bt2k_Insh.DLL)..Sicura di un vostro aiuto vi posto di seguito il log hijack
