Answer 2

Go to Tools>Internet Options>Connections>Lan Settings> Uncheck "Use a proxy server for your Lan" and you should be fine. Try scanning your computer for a virus, because that's what viruses do, they change your Internet settings so you wouldn't be able to access Internet.



OVERVIEW of what a proxy server is.

In computer networks, a proxy server is a server (a computer system or an application program) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.
