Is there software that enhances blurry photos?

You could try photoshop... if not, you can try copy/pasting the image onto Microsoft Word and editing the image there. The new Word lets you sharpen the image as well as adjust contract, brightness and colour. Last options would be to upload to walmart.com or walgreens.com and use the editing tools they provide when you make an account and upload images to order as prints... if you don't order prints, you can still preview the updated image, it will just be smaller than your original upload. (You can use the same features at in-store kiosks for either of those places)
