Ghost error logs?

My site keeps generating error logs even though I have them disabled in wp-config. Here is what’s in it:

define('WP_DEBUG', false);
define('WP_DEBUG_LOG', false);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);

And Defender Pro keeps flagging these error logs as suspicious files. Can you please help me figure out whats going on?
