Kaspersky is blocking /admin-ajax.php

Hi
My internet security program will block the page when pressing a color filter in the frontend. Then it will keep Loading and nothing will happen.
Kaspersky is writing, Dangerous URL-address is blocked. https://www.MyDomain.se/wp-admin/admin-ajax.php
I need the filter to work on computers with internet security installed.
Hope you can help.

Best regards
Kim
