Getting message Error JS:Agent-EIY [Trj] - false positive in website

Hello team,
I’m getting message “Error JS:Agent-EIY [Trj]” on a website that I’m developping and testing.
All the js files used in website are clean, downloaded directly from producter.
How can I solve the problem?
Website is: wxw.mzcase.it/tmp/
I used that files in other websites with no errors, so I can’t understand why this time they are blocked.

The blocked files are: (sometimes only two files, sometimes 6 files, sometimes all blocked)
wxw.mzcase.it/tmp/js/jquery.min.js
wxw.mzcase.it/tmp/js/popper.min.js
wxw.mzcase.it/tmp/js/bootstrap.min.js
wxw.mzcase.it/tmp/js/owl.carousel.min.js
wxw.mzcase.it/tmp/js/bootstrap-datepicker.js
wxw.mzcase.it/tmp/js/bootstrap-slider.min.js
wxw.mzcase.it/tmp/js/isotope.pkgd.min.js
wxw.mzcase.it/tmp/js/tail.select.min.js
wxw.mzcase.it/tmp/js/wow.min.js
wxw.mzcase.it/tmp/js/functions.js

I user Avast Free, ver. 22.5.6015- build 22.5.7263.726

Thanks in advance

Sorry, i assumed the browser would open the homepage without pointing it, instead it says list direcory denied (rightly so).

The homepage is: wxw.mzcase.it/tmp/index.php

Virustotal reports the file JS_sample.txt but this file doesn’t exists in website :-\

It’s clean…

A URL scan at VT is just a check against a number of blacklists, it does not scan the website but Sucuri does
