What causes HTML:Script-inf [Susp]?

I keep receiving a message about HTML:Script-inf [Susp] infection when visiting some websites. Here is the identifier of the error I recently received: 0640a063420b/2024-02-29T10:19:26.688Z.

What could be the problem that triggered this warning from the website? I am confident that the site is safe. However, I continue to receive the infection warning and cannot access the site.The issue is not only happening to me, so it's definitely not my PC causing it.
