Well there is still excessive information spread from the site: System Details:

broken links and redirects.
Only scanner to flag this site as suspicious among the major website scanners is Comodo Siteinspector on VT, but the actual scan is all green now:
http://app.webinspector.com/public/reports/17728037
Quttera’s still flags the conditional redirect: index
Severity: Suspicious
Reason: Detected suspicious redirection to external web resources at HTTP level.

This suspicious file flag denotes, mchain, that they are “not out of the woods” yet at that site, well I mean this security wise…
This file is being flagged by Quttera as it is found a top-level-document at HTTP level, and as such this is very dangerous practice,
because that way it grants the script maximum permissions allowed to control the web page in the browser (by malcreants).
This insecurity could lead to serious security and privacy breaches!
