Technical problem with Photoshop

I'm sorry if this question has already been asked but I couldn't find anything about it in the previous help posts.




I don't know what I did but now I have this sort of selection path around the picture in my icon. Plus it seems the path adjusted to the picture (I'd deleted the background and only kept the main character). It's very annoying to work with and I don't know how to get rid of it (and I checked that my capslock was off :-))
