Stumbled upon this on VW: http://zulu.zscaler.com/submission/show/543b6d556c9fd992c4361bee371ecfbf-1344967969
See: http://urlquery.net/report.php?id=129778
Site has WP theme arras flaws, arras theme is an present security minefield, read: http://design.j5mc.org/?tag=exploits (link author OMG Hax)
this also is incomplete code: thepcsecurity dot com/wp-content/plugins/wp-spamfree/js/wpsf-js.php  and suspicious
But apparently after one hour the unknown hrml malware there has been closed,
This website is not secure in sofar, that the full version number of the server software is being transmitted to the world.
Also through the "X-Powered-By" HTTP Header" the website gives away that dynamical content is being generated.
Also bad practice. Website also makes use of tracking Pixel  (1 x 1 px)
