How to un-blacklist a site?

Hello,

I'm taking a Udemy course on web development and the hosting site I need to use is blocked. The instructor assures me that the threat has been eliminated. Is there a way to get Norton to re-evaluate and unblock the site?

The site is https://safeweb.norton.com/report/show?url=thecompletewebhosting.com and is owned by Development Isle in the U.K...

Thank you,

CC
