sp176

I am excited about this new update, however when I installed it, I was immediately bombarded with users attempting to remote access my computer. I have never had this before, and it came as a shock. I use a firewall that normally allows me to let utorrent access throught the firewall. This allows me to individually allow access for each user. I normally do not have to even consider this under utorrent 1.6, and I share quite happily. Is this normal? Can I share torrents if I do not allow access to any users? How much access does a user have if I permit?
