I have a problem with the Windows Security popup below. It pops up every time the system tries to make connection with any internet source. It's very annoying, and I don't know how to resolve the problem.
(The popup window below is in Dutch, but says something like Connect to somedomain.com. Then it expects you to give your credentials.)
I am running on a Windows 7 x64 OS.
Now how do I solve this problem? Is it a Windows Firewall problem?
