Adblock Plus

Hello;
i want to remove ads on 1337x dot st, if you visit the page you will see ads below after main content, i am not worried about the position but the ads "material" which is not appropriate sometimes.

i used ADP block element feature but it didn't help.

When i looked viewed its source code, i noticed this ad is contained in a div class named mgbox, so is there any way to block entire div class on a webpage?
If yes how?

thanks

- main page or some speific page ? provide example link
- upload a screenshot with a page with ads (use imgur.com to upload the image then post here the link)
