[SOLVED] ShareThis plugin: need to delete text it placed

The ShareThis plugin has caused some residual code at the top of every page, and I don't know where to look to delete it. I have searched through Editor and am lost. I have also deactivated the plugin a few times, but it is still hanging out at the top of every page. How do I delete the code?

Could you please help me?
