When visiting your website, if you receive an error stating it's an attack page, that means that your website has been infected with a virus.
Your websites usually get infected by running old versions of software without updating them.
For more information about this, please read http://www.stopbadware.org/firefox
Please contact us if you need us to restore your site from a backup, however please note that by removing the virus, it will not remove the 'attack' warning.
You will need to request a delisting from stopbadware.org.
This has nothing to do with stablehost.
