The connection with update server has failed.
If you try to update AVG and receive an error message with the text Update failed. Connection with update server has failed., one of the following reasons may be the cause:
The connection to AVG update servers is blocked
If you are using a Firewall or a Content filtering applicaiton, please make sure that it is not preventing AVG from connecting to the Internet. If you are using Windows Firewall, AVG will be automatically allowed during the installation. However not all firewall or content filtering solutions offer this possibility. You can temporarily disable the program to verify whether it is affecting AVG, or you can add AVG files and servers to its exceptions. For a list of files used by AVG and servers to which AVG connects please see FAQ 3487.
Your Internet connetion is not fully functional
Your Internet connection to AVG update servers may stop working in some cases, althought standard Internet browsing works correctly. Proceed as follows to rectify such situation:
Your Internet settings are not correct
Even if your Internet connection is working correctly, incorrect DNS servers may be filled in, affecting AVG update. This can be caused by some virus that was previously on your computer.
You are using a dial-up connection
