Need Help With Removing Hacking Code

[coachbeafields]

Hello,

I am writing as it looks as if someone has hacked into my blog at http://beafields.com.

At the bottom of every page is a piece of code advertising something.

Like on the home page:

<div id='sp' style='text-align:right;'> CustomResearchPaper.net welcomes you to benefit from quality <a href="http://customresearchpaper.net/" target="_blank">research paper</a> now. | new version of <a href="http://convertyoutubetomp4.net/faq/" target="_blank">youtube to mp4</a> converter 2.0. | Wir bringen she Durch Die Erfolgreiche und Nachhaltige SEO Optimierung nach vorne!<a href="http://www.seo-beratung.in/" target="_blank">seo experts</a> </div> </body> </html>

Then, on other pages, I see ads for loans, etc.

I know that I cannot edit the footer in my themes. Any suggestions on what to do?

Thank you.
