I need a simple software that ideally needs minimal configuration that will completely block all incoming and outgoing internet connections on my computer, with the exception of a browser (Firefox) and uTorrent. I have tried a few different firewall software (AVG, Norton, Outpost firewall), but they all need configuration for each and every application that needs blockage, and most times those applications in some way can get around the firewall. Instead of using a blacklist based firewall, couldn't i use one that only allows connections from white-listed software? I would still be using my AVG software to remove viruses, remove Trojans, etc. so this software would need to be non interfering with my AVG firewall, and vice versa.

I am running windows 7 professional 64 bit, on 62KB/s Shaw cable.

Windows itself can do this. Just set the default rule for outbound connections to Block instead of Allow in Windows Firewall with Advanced Security (When you open the menu, right click and go to Action->Properties on the dropdown menu).

enter image description here

Once you have set it to block just remove/disable all of the outbound and inbound rules. Then make program rules for the only programs you want to be set to Allow. After that all programs will be blocked except what the 1 or two programs you want.

(P.S. You are going to want to allow AVG to update it's virus definitions too or else you will quickly become vulnerable to viruses and whatnot (same for windows update))

Is there an easy way to turn this on and off, I would like to be able to use this while using mobile hotspot to limit data usage. – Hugoagogo Aug 17 '15 at 0:52
@Hugoagogo Yes, you can easily make a powershell script to do it then make a shortcut to run the script on your desktop. – Scott Chamberlain Aug 17 '15 at 1:24
