If you notice in Eric's example, even pixels are sharpened and the slightest speck has a minor halo. It goes from a smooth background to a speckled background, despite being well out of focus.

Another process which can be (easily) overdone is Highlight and Shadows in Photoshop. It can bring out some amazing detail from the shadows but as the same time produces similar halos. The problem can go unnoticed because often the user is looking at the shadow detail and not noticing what's happening elsewhere in the image.
