How do I allow a website through Avast?

I recently have been trying to set up a script on a website I use frequently and I can not access my registration key because the server has hosted fraudulent websites before. coup-srv-01.comeze.com is what I’m trying to access and I need to know how to allow Avast! to let it through.

Site is infected, see attached screenshot

Ok, thanks. But, It’s supposed to redirect me to bungie.net
