Yeah. I basically combed all of the templates where the twitbox code was present and I deleted that code from all of my styles. I also deleted two suspicious plugins marked 'vbulletin' that had long strings of code marked 'Base 64.'

Just in case you haven't already, I highly recommend updating all of your passwords. I would also inform your community that you have been hacked and that they should ensure they have updated their passwords, especially if they aren't using unique passwords for different sites.
