Suddenly my settings in Firefox and IE was set to use Proxy. Security hole or virus?
When I turned off my laptop everything worked fine. When I turned it on again. It was not possible to connect to any website as the settings in both Firefox and IE was changed to use a proxy server. IP 127.0.0.1. Security hole or virus? Or maybe could I possibly, changed the settings by accident?
