Recent version of Viber on Windows started displaying ads. It appeared in sidebar under contacts. There is no GUI option to disable.
How can I disable them?
Owners of MikroTik routers who use DNS caching can create a static DNS entry on the router with Regexp field containing
ads(\-d|\.aws)?\.viber\.com and Address field containing
127.0.0.1. That will stop all devices on the network (phones, tablets) from showing those ads, not just a single PC or Mac computer like with the
Owners of Ubiquiti EdgeRouter devices can do the same but will have to create three separate entries because EdgeRouter does not support regex. Same goes for any other router or firewall, better to block on the edge.
