Hi,
Avast was complaining about this piece of code:
var url = 'http://jbcdv.net/dm-sso-endpoint/1445153201/?dm_action=domainmap-check-login-status&domain=nwetc.com.au';
var iframe = document.createElement('iframe');
(iframe.frameElement || iframe).style.cssText = "width: 0; height: 0; border: 0";
I made it so it is not detected, but please do keep in mind that this behaviour can trigger AVs, as they are checking for hidden iframes as well.
