Adsense auto-inserting, run amuck

Apologies if this is the wrong forum for this, seemed like the best spot.

I have no template instances of google_ad_section_start, yet for some reason they're showing up in my source anwyay. They're all over my source, in fact.

Here's a snippet:

<img src="http://www.sevenstring.org/forum/./geek/gars/images/2/3/et.jpg" border="0" alt="<!-- google_ad_section_start -->Sevenstring.org Review: End Theory<!-- google_ad_section_end -->" />

None of those are actually in my postbit, or any template. There's about a dozen of them on the page. What the heck is going on? :\

Here's one of the pages it's happening on:

Toss that into validator.w3.org, and look at the source. They're all over the place!

Edit: Found it, it's part of vBSEO.
