question: DNS leaks while using the ExpressVPN Windows app with antivirus or online security applications
answer: 
  This guide will show you how to resolve DNS leaks when running antivirus or online security applications with the ExpressVPN app.
  
  When connected to ExpressVPN, your device runs DNS queries using ExpressVPN’s secure DNS servers.
  
  If you use the ExpressVPN app along with an antivirus or online security application such as Norton 360 and Avast, the antivirus or online security application may interfere with the ExpressVPN app and instruct your device not to use ExpressVPN’s DNS servers. This may result in DNS leaks.
  
  To resolve this issue, follow the steps below. After each step, run the leak test to see if the issue is resolved. If the issue is resolved, you can skip the rest of the steps.
  
  Before proceeding, make sure you are using the latest version of the ExpressVPN Windows app.
