iThemes Security on my .htaccess although plugin is not installed

Hi guys,

I was adding some stuff to my htaccess and noticed that there are several lines by iThemes Security.

I don’t have the plugin installed (neither I had it installed before). How is this possible?

This is the code I found:

# BEGIN iThemes Security
	# BEGIN Hide Backend
			# Rules to hide the dashboard
			RewriteRule ^(/)?entrance/?$ /wp-login.php [QSA,L]

	# END Hide Backend
	# BEGIN Tweaks
		# Rules to block access to WordPress specific files
		<files .htaccess>
			Order allow,deny
			Deny from all
		</files>
		<files readme.html>
			Order allow,deny
			Deny from all
		</files>
		<files readme.txt>
			Order allow,deny
			Deny from all
		</files>
		<files install.php>
			Order allow,deny
			Deny from all
		</files>
		<files wp-config.php>
			Order allow,deny
			Deny from all
		</files>

		<IfModule mod_rewrite.c>
			RewriteEngine On

			RewriteRule ^(.*)$ - [F]
		</IfModule>
	# END Tweaks
# END iThemes Security

Any ideas?
