Your router may be affected by a new malware targeting it, more technical details here.
If you have access to your router and know how to manage it, first of all restart it. This alone will clear the temporary data used by the malware - but it's due to be re-infected if you do not upgrade your router's firmware to the last version available.
In the case you do not manage the router, ask your administrator or service provider if your router is safe from the VPNFilter attack.
