When i go to certain websites a username/password window pops up. The window is titled adserver.adtech.de and obviously asks for a username and password. If i click cancel a few times the window disappears and i am able to browse the website normally.
I have messed about with my computer a little to see what could be causing this. What i have found is when my hosts file only contains 127.0.0.1, i dont get the username/password window, but when i download the hosts file from http://www.mvps.org/...p2002/hosts.htm i get the username/password window again.
So does this mean my computer is okay and the username/password window is being caused by the hosts file and nothing else? It would appear so to me but i am asking because i don't know of anyone else with a similar problem, surely other people would be getting the same problem?
Any advice appreciated, thanks
