p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.

This looks like it could have been a vector file at some time in the past. I would first try if I can get hold of that vector file. Would be some much easier to edit and a lot better quality.

But if that is not possible:First of all Alt-click the Background layer to make it an image layer so that a transparent background is even possible.

Set the Magic Wand tool to something like 16 and also set the option so that it selects only neighbouring pixels, Click in the blue background. Enlarge that selection using Select > Edit Selection > Enlarge (or similar - I have a German version). Widen it by a few pixels (depends on the size of that image. If you want the white border to stay in that same width, then you would have to watch closely and zoom in). Then delete.

You could perhaps get a cleaner result by using the pen tool for the selection. But it needs some routine to master.

As this was almost certainly created as a vector object, as Monika has said, it's a perfect example of when the Pent Tool should be used to create a clipping mask.  If you are not familiar with the Pen Tool then these videos from Michael Hoffman are excellent.

Hoever if you want a quick soloution there is a wee pearl in the Properties panel that I suspect is missed by most people.  Note I have pasted your image into a new document and increased its size to 1000 pixels wide.  So select your layer and at the bottom of the Properties panel there is a Remove Background button.

Hitting the button creates a layer mask, but has left a fringe of the background colour.

There are multiple ways of fixing the fringe, but a method Jesus Rameriz of The Photoshop Training Channel suggests is Filter > Other Minimise 

With the layer mask still selected, open the dialog for that filter and make sure that the Preserve option is set to Roundness.  Note I have turned off the background layer to make it easier to see the best value to use.  I used 2.0 but remember that I increased the image size so it might be different for you.

It's actuially done a surprisingly good job.  I was expecting the sharp corners to rounded, but that did not happen!
