I've installed the Better WP Security plugin and since my site went live last week, I've received daily emails of dozens of file modifications that I'm not aware of (i.e. different to when I've added a new blog post or image etc). It refers to a Really Simple Captcha plugin that I don't have installed - should I be concerned? There are dozens of file modifications daily that read like this:

Sorry for my ignorance, I'm just learning how this works!
