When I try to moniter, a box pops up saying;

Your client is a leaf node shielded by an Ultrapeer.
Hence you will see few or no searches in the moniter window.

Can someone please tell me what this means? I'm thinking it has something to do with my anti-virus/firewall. I use Bit Defender 8 Professional Plus. If it has to do with that, than how do I fix it?
Any help at all would be greatly appreciated.
Thnx!
