@wfasa - thank you for that information it's helpful.
So what you're saying is that any file containing my domain name would produce a warning about that file?
That's curious, because for example WordFence is giving me warnings for about 35 images on my site: "Post contains a suspected malware URL" - where the URL in question is the link to a .jpg I've uploaded. But it's not giving me warnings for ALL the images I've uploaded to my site.
If what your'e saying is true, then how come WordFence isn't telling me every single image on my site is potentially unsafe??
