Well anyway try to have it outside that 173.201.216.98 to 173.201.216.98 range and inform them about the p3nlhwst019.shr.prod.phx3.secureserver dot net/ authentication issue and why avast! is blocking it.
Also consider the Netcraft risk rating (7/10) here: http://toolbar.netcraft.com/site_report?url=http://secureserver.net
and the web rep: https://www.mywot.com/en/scorecard/p3nlhwst019.shr.prod.phx3.secureserver.net

P.S. I see no issues in the code on your site, example: http://server15.kproxy.com/servlet/redirect.srv/stluq/szlzf-lq/p1/file-viewer/?tgt=http%3A%2F%2Fwww.noelinvestigations.com&ref_sel=Google&ua_sel=ff&fs=1
