Changing your DNS settings to troubleshoot issues with AVG products

 

Problems with the DNS servers from your internet service provider can compromise the functionality of certain AVG products. You may experience the following issues:

  • AVG installation or update repeatedly fails.
  • AVG does not accept your valid activation code, so you are unable to activate a paid subscription.
  • AVG Secure VPN cannot establish an internet connection, or you cannot browse the internet while connected to AVG Secure VPN.
  • AVG Secure Browser does not allow website access.

To troubleshoot these issues, AVG Support may request that you change your internet connection settings to use DNS servers from a different provider, such as Cisco, Google, Cloudflare, or Quad9.
