Update is supposed to be automatic, this message box appears everytime I connect to the internet.
Window XP, Firewall??
Thank you

Is this message similar to the pages stored into <avast>\English\HtmlData\ ?
Where <avast> is the main installation folder and English could be your language.
Error 404 occurs when a webpage is not found (server unavailable).
Which is your startup page?
Can you browse after opening the browser and receiving the error or not, you can't browse anyway...?
