mike,

If you have a Firewall such as Norton Personal Firewall - DISABLE IT. Then try again to connect to the AVG site and try downloading the file. Sometimes a Firewall will not allow access to certain sites and or files. See if that helps. If you don't have a Firewall make sure all your security settings in your Browser are set to "default". Also if you have an existing anti-virus program on your computer try 'disabling' it to see if that helps. PS: After you try to download the file again, whether succesfull or not, don't forget to re-enable your Firewall and Anti-Virus programs afterwards.

Best regards,
Mike
