A while ago I downloaded a little tool called silencer,
This is how it was described:

Silencer offers a different approach. It can be used if you would like to keep the adware product but not have it communicate. It disables communications between your adware and its "mother ship" by disabling the latter's URLs in your hosts cache by pointing them all to 127.0.0.1 (or any other IP). Please note that although you are justifiably upset that these stealth communications are going on in your computer, you might actually be in violation of your EULA if you disable them - so use it for educational or troubleshooting use only.
Works with: all (generic)
Note:
If you decide to remove the application later, you need to delete the file C:\Windows\hosts and reboot your machine. If you do not delete the HOSTS file, you will continue to block the servers that you added.

I haven't checked myself if it works but as soon as i done I let you know, unfortunally I can't seem to find the url that I got it from
