RS Joomla Firewall throws this up

After running a scan in RSJoomla Firewall it classes the following as suspicious JS Inclusions

administrator/components/com_hikashop/extensions/plg_hikashoppayment_epay/epay_end.php Suspicious JS inclusion ssl.ditonlinebetalingssystem.dk/integration/ewindow/paymentwindow.js" charset="UTF-8
administrator/components/com_hikashop/extensions/plg_content_hikashopsocial/hikashopsocial.php Suspicious JS inclusion assets.pinterest.com/js/pinit.js"></script></head>
plugins/hikashoppayment/epay/epay_end.php Suspicious JS inclusion ssl.ditonlinebetalingssystem.dk/integration/ewindow/paymentwindow.js" charset="UTF-8
plugins/content/hikashopsocial/hikashopsocial.php Suspicious JS inclusion assets.pinterest.com/js/pinit.js"></script></head>

are these files all necessary or should i remove them?

thanks

These are not suspicious.
They are necessary in order to use the epay gateway and the pinterest API.
If you're not using the social network plugin and the epay payment plugin you can remove them but it won't change anything.

These are just false positives.

sorry for late response.. thanks that was good to know
