Your router is infected!

Your router has been compromised and your network connections are being routed through a malicious remote server.


Before trying to solve this problem, make sure to solve all other router problems detected by Avast. Otherwise the following fix will not be effective.

To configure a wireless router:

  1. From the Wi-Fi Inspector results screen, select Go to your router settings to open the administration page of your router.
  2. Enter your router username and password, or contact the party who provided the router (e.g., your ISP).
  3. Find the Internet settings section (may be listed as WAN, Connection, Broadband, or Basic settings/setup, etc.), or the separate DNS configuration section.
  4. Make sure all of the following services are disabled (if available):
    • DNS Relay - Disabled
    • Advanced DNS - Disabled
    • mydlink - Disabled
  5. If your ISP supports automatic configuration:
    • Set up Internet, or WAN connection type, to Automatic Configuration (may be listed as DHCP, Dynamic IP, or Auto, etc.), or set up DNS configuration to Automatic Configuration (may be listed as Obtain DNS from a WAN, ISP, or Auto, etc.).
    • Ensure that all DNS server records are blank, or set to, i.e. IP with zero values (this applies also for static DNS records, if available in your router's LAN or DHCP settings when a local DHCP Server is Enabled).
    - otherwise -
    If your ISP doesn't support automatic configuration (e.g. Internet, or WAN connection type is set to Static IP), fill in DNS server fields with IP addresses of reliable DNS servers, such as Google Public DNS, as shown below:
    Primary DNS:
    Secondary DNS:
  6. Confirm your changes (select Save settings, Update, OK, etc.), and reboot your router if necessary.


Due to the wide range of different router types, we offer vendor-specific instructions for frequently used routers or general instructions for all other routers. For exact instructions please consult documentation for your router model or contact your router's manufacturer for further assistance.
