Running build 13582 on my laptop. Haven't had any crashes, freezes or slowdowns but it does waste a lot of bandwidth. I'm on a 1 meg connection and when downloading at 20kB/s (160kb/s), my web browser slows to very slow speeds. And I have added uTorrent to NOD32's exceptions. also, when running uT 1.8.1 I can browse the internet very fast
