Il mio ISP sta iniettando strani codici per ogni sito web che visito

Ecco il codice in fondo a ogni pagina:

<script type="text/javascript">if(self==top){var idc_glo_url = (location.protocol=="https:" ? "https://" : "http://");var idc_glo_r = Math.floor(Math.random()*99999999999);document.write("<scr"+"ipt type=text/javascript src="+idc_glo_url+ "cfs.u-ad.info/cfspushadsv2/request");document.write("?id=1");document.write("&amp;enc=telkom2");document.write("&amp;params=" + "4TtHaUQnUEiP6K%2fc5C582NgXaqsgjSGNd2cIJOj4fGdzujsIEimxj4UPJYe9kNVgJGL7lyzhXKfrFGnoI%2b0vRYDgH9e8pX4n5Ajpp2c31FAwDlsLBVPPzlithe%2b39AiTY5lcCtK5vmMReu6wh%2bDE9aF7GU5vhghexF8DVA5RGi1nSH%2b4LUQNJ2rgvBZQRGaRUEas7vndUsAU7ZB2kVVd21uWsDGzo5RfMV2LGQF5uvtQQLl0Ism%2f7TwrUdQb5rPOdOsuSNgCzf7cTnxOizeAF5TqCrR5TPbRFuCEbu1j0vYkDTFuj9EdyZbRxAaO9KaZ1VpIEUKC3XEDAXKf0X3XDCyG3gvQoMWun2ueK8dLkFXlxSf9N4HI19gTZgGjR6Yc6QWGdE220AehWZepv%2bai9rUvHBo8xGo5pesp2qLykCKOPvJaq0IlaAunmzO0iLn9hkvy%2bl3BA8crhs3KdFymg9sCqjZ016F5XxGxpvEP64Se5R%2fSVPWjmyrXRo0Hj%2fR5W2wmR5oVAqGo6XAIYvQPj%2fay6rRypz%2fdDgohPBqd3g9wGYkzKmh9CjDSiozL4BrH2xmRhjAwbe9WTBc%2f45LdcqT4sjgnuTFy");document.write("&amp;idc_r="+idc_glo_r);document.write("&amp;domain="+document.domain);document.write("&amp;sw="+screen.width+"&amp;sh="+screen.height);document.write("></scr"+"ipt>");}</script><noscript>activate javascript</noscript>

Codice riformattato per la leggibilità:

<script type="text/javascript">
if (self==top) 
{
    var idc_glo_url = (location.protocol=="https:" ? "https://" : "http://");
    var idc_glo_r = Math.floor(Math.random()*99999999999);

    document.write("<scr"+"ipt type=text/javascript src="+idc_glo_url+ "cfs.u-ad.info/cfspushadsv2/request");
    document.write("?id=1");

}
</script>
<noscript>activate javascript</noscript>

Per quanto ne so, gli script risultano in:
1. Annunci pubblicitari in cima alla pagina.
2. Un altro script, assomiglia a questo: (penso che provenga da tutti document.write )

<script type="text/javascript" src="http://cfs.u-ad.info/cfspushadsv2/request?id=1&enc=telkom2&params=4TtHaUQnUEiP6K%2fc5C582NgXaqsgjSGNd2cIJOj4fGd5RLjWCROmlHIy48LIQTADgF3HH0Ey1rugHzqHqlMdHhjWGhSoLYV7pNQv4xROBLa3av9%2fC4NiY3j2JGTEsNtntuZbGJY6AcrFAxBU%2bl2v%2fP7UmpGL4oPTkrnZHz2siuHgJObfiz9o2uFZcO0r5u9yM9Hb9%2fxVMO5q2x880snCrSpl0W78pEGN9bkMf0L3sntEalc9JCGeOgb0Sq8Na%2bsPstohxMNLoxwUZzykryNagI6%2f97%2foigL7WlQibMgu7KLaJuvZRRYZAe56XBzGCV0Dd8hZMaqNSy%2bsf6U%2fGFtjczEXqcbHmTYb9CN%2fM%2bBp85oqvoYceLPyxOEvGtM%2f3cZitomHRmFvN5Iczk%2fAhExnvnRD1PulZ1mM7ESsBXyW3MVYIPD5IgxsP0pakjCfcJVA7PWyrNPt2MdgS%2bEeBDVs6vwiFe4pvuYzp%2f7xQfwQCEp%2fzYMYURDk147O8N8xLBb0GAw7j2%2bleN0JEJdAN8cPFMleFkkswZJQ9pozHFOUKaICQr3f27Qe4dh5ZOeWx%2fug&idc_r=89214501948&domain=sparklingchix.com&sw=1920&sh=1080"></script>

Sevisitil'URL: link .
è una pagina di accesso di "Push Ads Management System" versione 2.0
3. Nella pagina in basso, c'è un iframe come questo qui sotto: (nota che invia anche un dominio del sito web che sto visualizzando)

<div id="pushstat" style="visibility:hidden;height:0;width:0">
    <iframe src="http://stat01.u-ad.info/push.stat/stackoverflow.com"></iframe>
</div>

L'iframe risultante contiene uno script di Google Analytics !
(Quello che inizia con function(i,s,o,g,r,a,m) )

Le mie domande:

1. Cosa significa tutto questo? Volevano solo mostrare annunci o volevo raccogliere le mie statistiche di navigazione?
2. Come posso bloccarlo?
