Red Squares Showing up on images - 60D

[Meredithjewel]

Hi everyone - I need help with fixing these mysterious red squares that show up on my finished images while i'm editing them. I have no clue what causes them.

I'm going to include a screenshot of one of them on an image i pulled up to edit in Lightroom.

what has touched your image before this, i.e., what is your workflow?

Does it show up when you render a final image, or only when working on them? i,e, is it an image data problem or a preview problem?

Nothing, this image is straight from my camera to my laptop - no edits were made prior to the screenshot. It only shows up on (seemingly) random images as well, I was shooting for about an hour straight and 2 images have these squares on them. 

The square shows on the preview on my camera as well.

This is possibly image corruption. When was the last time you formatted your card?

You need to do the basic trouble shooting first off. New SD card.  Reset the camera. Try it in a nice bright day lighted place. If it works, it works. If not it needs repair.

You said it was on the camera's screen also. That eliminates LR and your computer.

just a thought, do you happen to have a heat source with this shape in your studio?
