Avast blocking legit site after update

I’ve reported this at the Contact link, but I don’t know how responsive that might be and I saw that there was another similar thread that got a quick response, so I’ll post here, too.

Suddenly started getting Webshield warning after updating Avast Free on 2/21 - HTML:Includer- AY[trj]. I access this site often, for part of a class action suit, redeeming award. Suddenly, I get this warning on almost every page. Please check this? Thank you!

Thank you for the links… but that tells me that …what? It’s a known problem? That it’s a false positive? That it’s a REAL positive? That I access the site at my own risk?
