My Website being blocked as malicious

hello,

my website is being flagged and blocked by avast as a malicious website. xxx.harmoniatango.comxxx
I have check the site with Urlvoid, Urlquery etc … but it is clean except on a check with Quterra that detected a suspicious file that is just a font plugin (see attachement).

What can I do ?
thanks by advance for your help
Steph

Just being resolved … don’t know how and why !
I suppose the avast Staff did great job ! thanks

Moderators : perhaps you could delete the post as it is resolved wihtout helping solutions for others ! Thanks
