Infected WordPress Installation

Well, it looks like this site has managed to become infected with the “WordPress Pharma Hack” and I can’t seem to get rid of it.

If I can’t get rid of it soon I will abandon WordPress all together. I wish I could figure out why this has happened, but I just cannot see why.

I’ve followed this Pearsonified article on how to remove it, but I couldn’t find anything on my site that matches his recommendations. In the meantime I’ve removed every template and plugin I don’t need. I’m now using the default template, no other templates installed, and I’m down to a small set of plugins. I’m going to disable a bunch and see if that makes any difference.
