發生這個問題的主要原因是, 使用者需要透過代理伺服器連線至網際網路. 案例其一, 你已經為瀏覽器設置好代理伺服器了; 如果是這樣, 則可直接採集瀏覽器之中的代理伺服器設定並輸入到 Spybot-S&D.

In Mozilla, you can find the Proxy settings if you open the Edit menu, choose Settings... at the bottom, and navigate to the section Advanced - Proxies.
In Internet Explorer, see the Menu Extras - Internet options, go to the tab Connections and click the Settings button at the bottom.

Back inside Spybot-S&D you need to go to the settings page, and scroll down to the entry Automation - Web update - Use proxy. Now check the box below it, and a dialog will appear where you can enter your proxy settings.
The format is host:port (the host is the name, the port the number you found in your browser). If you need to access your proxy using a login, you can use the format username:password@host:port.
