What details you want? I dont know why i cant access too… I have Google Chrome and Firefox…
I can acess by my smartphone, but on PC doens’t work the site…

What happens if you try to open https://www.avast.com in Firefox ?
What happens if you try to open it in FireFox safe mode ?

O Firefox não consegue estabelecer uma ligação para o servidor em www.avast.com.

O site pode estar temporariamente indisponível ou demasiado ocupado. Tente novamente dentro de alguns momentos.
Se não conseguir carregar quaisquer páginas, verifique a ligação do seu computador à rede.
Se o seu computador ou rede estiverem protegidos por uma firewall ou proxy, certifique-se de que o Firefox tem permissão para aceder à Web.

I’ve had the same issue last night. Is this all the time or does it go away after 20 ~ 30 minutes?

How are you connecting to the internet on your PC?

dbrisendine,
the OP said he could open the site with the SafeZone Browser.
I’m thinking more about a plug-in blocking it.

The you are on the right track with Safe Mode for FireFox to check the add-ons / plugins.
