title: Can't remove a "security" folder from the server via FTP
body: <p>I currently host a website on Hostgator. My site redirects to an Adobe Flash Update automatically. I contacted support at Hostgator and they did not want to help, they said I need to contact sitelock to remove the malware is causing the redirection.
  I ftp in to the server and found there is a ".security" folder which seems to be the cause of the problem. It has some zip files and other php files. I cannot change its permissions nor delete it. 
  Does anyone knows how can I remove this malware from the server? Any help is welcome thank you. </p>
