What are your settings for the connections and proxy?
Right click on the system tray icon, choose 'Start avast! antivirus' and then, right click the 'skin' (program) and choose 'Settings'. Go to the Connections page...
How do you connect to the Internet? Dial-up or DSL?
Do you use a proxy or not? If you don't know what is it, you don't use one...
