Kaspersky is blocking my xbox wireless connection.

I have kaspersky antivirus installed on my computer.
I just setup my xbox to work wirelessly. I see rss and weather and last.fm works but is very choppy. They only work when protection is paused on kaspersky. So i figure it's blocking it.
I also cant see my xbox in the wireless devices or anything, but i can ping to it.
How do i unblock my xbox from my antivirus??

-Im using a linksys wga11b adapter that connects to the internet thru my windows vista laptop which is wirelessly connected to my home network.
