if you want a free firewall with full control then I always recommend Comodo. Just gotta set it to verbose mode and few other settings like "create rules for safe applications" and so, so that it asks you everything. Then I can imagine you can block all of that with ease.. Although many find asking for everything annoying, I just love the control it offers. Definitely my favorite security suite for long years now. It also has a defense+ which gives a detailed control over actions between applications, hooks and so. Also with antivirus and many other features. And also the paid version offers absolutely nothing I would want. (100% virus free guarantee or they pay you money, or remote expert assistance or such) Not trying to advertise, but it really deserves it from my point of view. Also, I guess you could also block it somehow over hosts file, just not sure if it would conflict with updates or so.
