Create firewall “profiles” for Windows 7
Sometimes my home internet connection drops, and I have to switch to a tethered mobile one which has a data limit. This means I have to close pretty much all applications except a fresh internet browser to make sure there are no bandwidth-wasting applications running.
I'd like to know if there is a program that lets me block all programs' internet access by default, and use a whitelist to let applications through this block. On/Off switch would be nice, but closing the program and then re-opening it when I need it again is fine too.
