Fake anti-virus looks like your OWN AV!

Came across this page today while search for something on the net. It is a page that tries to make you think your computer is infected and that it is your own anti-virus telling you. It is not however but instead is an image that comes up based on what anti-virus it detects that you are using.

Here is the source code from the page:

<html>
<head>
<title>Viruses were found on your computer!</title>
<script>
window.moveTo(0,0);
window.resizeTo(screen.width,screen.height);
</script>
<script>
var ask=1;
var text='Viruses were found on your computer.\nYou need to clean your computer to prevent the system crash.';
function al(){alert(text);}
window.onbeforeunload=function (){if (ask==1){return text;}}
</script>
</head>
<body topmargin=0 leftmargin=0 bgcolor='#FFFFFF'>
<table cellspacing="0" cellpadding="0" border="0" width="100%" height="99%">
<tr valign="middle" align="center"><td>
<img id="al" src="images/alert.png" width="617" height="345" border="0" usemap="#map">
<map name="map">
<area shape="rect" coords="544,12,593,33" onmousedown='al();'>
<area shape="rect" coords="480,287,578,308" href='download/' style='cursor:point' onmousedown='ask=0;'>
</map>
</td>
</tr>
</table>
<script>al();</script>
</body>
</html>

There is a copy of this image on imgur not uploaded by the scammers but by scam investigators. They added a warning on it so that it can't be used on similar pages:
