Binos,
Try
www.k-lite.tk
K-lite or Kazaa Lite or K++, call it what you will, is Kazaa with the adware stripped from it. I have used version 2.0.2 for some time and it's fine.
You'll be redirected from the above link. Go to downloads. Latest English version is 2.1.0. Get the latest codecs as well, version 1.6.
Good luck, don't despair.
