Google is showing my site has been compromised. I checked the server and did in fact find several files that were put there by someone else; these have been deleted. Though there was an .ftpquota file associated with the hacked files [which i deleted], I also noticed a .ftpquota file in a folder unrelated to the folders where the hacked files were. I've tried to find out what this is. What i've learned is that it's put there when a new ftp user is added. None have been. It also seems sometimes it's automatically put there by the 'cpanel' ... anyway, what i really want to know is if i can delete it....knowing no other users have been added?
