Annoying ads

Hi!

I have a problem on my forum - on top, under the logo and titile of the forum there are annoying ads. Some of them even look like viruses ("you've won a prize, click here to claim it" a stuff like that). Is there a way to get rid of them? Some of my members don't even like to come on the forum enymore because they think they'll get a viruse or something. What should I do?

Thanks!

Anyone?

May I remind you that double/triple posting isn't tolerated unless separated by 24 hours (Use the edit button)

You can disable ads on your forum for members & guests by purchasing Credits. Please read this topic => here

Sorry, I didn't know that double/triple posting isn't tolerated. So I read the topic and as I understand I have to buy Credits with real money? Hmmm... And what if my country isn't listed? What about the donations from members - they can donate but not real money? Could you please explain this to me. I'm kind of new here so I don't know how this goes.

Thank you!
