My site is blocked. Please, help

I am very very very disappointed with support service of avast. I created a ticket 3 days ago with tag “urgent” and two more later. Unfortunately, there is still no answer. I wrote a message to Avast Facebook page. It turned out that some people having the same problems with support. Via avast program interface I also sent many times the notification that my site is clean.
Please, help to solve my problem.

Somehow my site is blocked by avast. I know for sure that the site is clean.

I bought a domain vtset.com 6 month ago and did nothing with it. It was an empty directory on hosting provider site. A week ago I decided to begin my work with this site. And found out that it is blocked by avast. After this I downloaded working site from Denver, but it is blocked Avast and no answer from support. Please, help.

My site is unblocked. Thank you everybody who helped!

there can be many reasons for a block, it does not have to be infected

if avast say URL:mal it means your URL or IP is/was on a blacklist … for whatever reason
