Avast Threat: html:script-IMF

Avast keeps aborting my connection to htxp://www.arthouseconvergence.org and all pages “because it was infected with HTLM:script-inf [Susp]”

I’ve tried in two different browsers. This is a non-profit organization that should be safe. I’ve checked the site on
https://transparencyreport.google.com/safe-browsing/search
https://global.sitesafety.trendmicro.com

and it came up safe on both.

Is there any further safety check to do or is it ok to add the website to Avast / Settings / Exceptions?
