Avast reports phishing from wix website

Good morning,

It’s been a few days that Avast has been reporting phishing from this website I manage : https://webmaster50050.wixsite.com/terreux-armoricains
I’ve had alerts both on the website builder side as well as downloading any pdf file (“Téléchargez notre plaquette button” for instance)

Could you please help me determine whether it’s a true or false positive and possibly getting rid of either the malicious code or the false alarm ?
