I recently had a keylogger on my computer recording usernames and passwords including their respective web addresses. I have changed all my passwords however on my web hosting account, in the FTP, there are numerous copies of the same exact file. For example:
Original file: index.html
100+ new copies: index.html298fmla9g9dlandkf ... with random characters.
Should I be worried? They are clogging up space on my server and they're horribly tedious to delete. My server went from 3gbs taken to about 45gbs taken.
