Clean website still blacklisted in database

Hello,

Our website was attacked by hackers a few weeks ago, and now it’s clean. But as it is still blaclisted in Avast database, people who have Avast installed on their machines can’t display the website correctly (extremely long to display, or no display at all).

How can we get the website reference out of the database ?

Thank you for your help.
