Avast and xbox..... can't connect!

Hallo,
i have installed avast home on my w2000, but now i cannot connect to the pc from my xbox, using XBMC…
i tryied to stop all the provider in avast, but it didn’t solve the problem… every connection is refused…

i didn’t change nothing in pc configuration, only installed avast home.

did you have any suggestions?

regards
DBL

are you using the beta build version 4.6.718? To check go to the blue ball with an
a on it and right click and click on about avast then the click on the + sign by avast verson 4.6 home edition then look at the build.
