No matter what you do, they are easily able to access everything that you type on your computer when this happens. You can find a good deal of antivirus programs that are good on the Internet. Search for a antivirus program or ask experts about this.
Move your wp-config.php file up one directory from the WordPress root. WordPress will look for it there if it cannot be found in the main directory. Additionally, nobody else will be able to read the file unless they've SSH or FTP access.
Now it's time use this person's name and identity to present as your friend and to register for a new Facebook accounts.

Do your homework and some try this site searching, but if you are pressed for time and want to get this done once and for all, try the WordPress security plugin that I use. It's a relief to know that my website (and company!) are secure.
