false positive HTML:Script inf

For a few days when I access my website hotelmarketing.school avast detects that it contains malware and does not allow browsing the web, I attach a screenshot of the detection. It is a false positive because the web does not have any malware, please do so that Avasta does not make this erroneous detection or indicate the procedure to follow so that this does not happen.

Thanks in advance

Greetings

sorry forget attached the image

No screenshot attached, see my attached image to see how.

I have captured an image of the (just the alert window) detection given for you anyway. This way it isn’t a full screen capture.
