This is a defacement attack conducted by members of the Muslim Cyber Army, mainly from Pakistan. On hacked sites they usually add files like Romantic.html, PK.html, Intruder.html.
It is quite common for them to compromise whole servers when they are not properly secured.
Any web site (no specific target).
Restore your site from a clean backup. Deleting all files first is the best option since it will delete all backdoors and other malicious files that
hackers could leave on the server. It is important to identify and close the security hole to prevent recurring attacks. Make sure that file and directory permisions don't allow to create/modify files from other server accounts.
