How do you unblock a website in Avast?
First, I’m an Avast user and not an Avast Team member.
What do you mean by ‘unblock’ - is avast Alerting on the site or are you getting an error message at the site ?
If the former a screenshot of the Avast Alert window might help.
Create a screenshot on your computer and save it locally. Using windows explorer or other file management program, drag and drop into your post.
