Hello
I have been using avast products for years (most free version) but recently did i want to try your vpn, which really surprised me when it comes to performance & speeds on connection
But then i looked on your vpn location, and figured out you not have vpns in denmark.
So iam asking very nicely if you any plan on installing a vpn in danmark in near future ?
Sorry. if this not are the right place for suggestions 
Ofcourse it is possible to have a vpn servers in every country (unless a country refuses to allow it).
But there are 196 countries in the world (depending on what country you ask).
That would mean a huge infrastructure to setup and maintain which the corresponding costs.
I don’t know avast’s policy when it comes to where they setup/have vpn servers, but I can imagine that Denmark is not somewhere on the top of the list where avast is planning to have servers as it is (just like my country, The Netherlands) a very small country.
