My website repeatedly appears as dangerous. is a false-positive issue that occurs again and again.

My website, which is in Spanish and contains the letter ‘Ñ’ (ñoñosmagazine.cl), is repeatedly flagged as dangerous by AVAST. Every time it gets flagged, I report it, they fix it for a while, and then it gets flagged again. The site only contains static HTML. It is not phishing or anything similar. What can I do to stop AVAST from blocking it over and over? It is affecting my business.
