Game Uses All My Bandwidth

[Strill]

Title: Game Uses All My Bandwidth

Version: 3.0.3/3.0.4

OS: Windows 7 Ultimate

Java Version: 1.7.0_03

Description of Problem:

After installing Tekkit, whenever I try to connect to a multiplayer server, under Tekkit (or Hack/Mine) java.exe opens a connection to 207.171.187.117 (amazon.com) on port 80, and uses up all of my bandwidth (42KB/s). The multiplayer connection fails because there is no bandwidth, and the bandwidth usage continues even when I return to the title screen. I've been monitoring this for about 30 minutes now and the bandwidth usage still hasn't stopped.

This never happened until I installed Tekkit. What's going on here? Is this some kind of spyware?

I'm sorry I can't help you fix this problem, but I think this may be happening to me too. Could you please tell me where you found out that this connection was opened? I am using 5 GB/day that are unaccounted for.

I used NetBalancer to check my bandwidth usage and connections.
