Introduction

ZION SECURITY was contacted by a company to verify the security of their web site.
Their web site was added to the Google Safe Browsing blacklist. This resulted in search engines adding a disclaimer "visiting this site can harm your PC" to the site and Firefox would give a big warning that the web site is infected with a virus.
