URL:Blacklist false positive?

I newly installed Avast Free antivirus.
From youtube, I clicked on a link to https://thegameroom.tv and received the Threat secured message.
We’ve safely aborted connection on www.thegameroom.tv because it was infected with URL:Blacklist.
URL: https://www.thegameroom.tv/templar-builds
Process: C:\Program Files\Mozilla Firefox\firefox.exe
Detected by: Web Shield
Status: Connection aborted.

Testing www.thegameroom.tv on : https://transparencyreport.google.com/safe-browsing/search?hl=en
Google returned the following: Current status No unsafe content found
So would it be possible for Avast to check www.thegameroom.tv and if clean, remove www.thegameroom.tv from the URL:Blacklist list?
Thanks for reading.
