other than that.. i have no idea what it could be..
other possibilities, browser might have a free vpn option, i know Opera has it and I disabled it. but that depends if you use battlelog to play game, if you dont then thats all i can think of. Maybe reset network connections, by going into troubleshooter by right clicking on your network icon on botttom right and follow steps and it should reset your network connections.. also check network connection. right click on network icon, select Open network & internet settings, click on Change adapter Options. in there it should show all the networks you have directly connected to, if there is a vpn it should show it there.
