Clone tool or spot healing brush. It's a classic perfectly spherical dust-spot so simply adjust the size of the clone stamp/spot healer until it's just a bit bigger than the blemish, then apply with a single click. If it looks OK, great, but you may (may) have to re-adjust the size of the brush (i.e. make it much smaller) and smooth the edges.
One thing I've wondered - is correcting dust-spots in this manner acceptable? Surely this is classed as photo manipulation and therefore a bit of an A.net taboo?

Karls advice is valid but basic,
I would put money on your original image having more than one dust spot*
The most effective way (apart from keeping your sensor clean) is to make a duplicate layer -
-LAYER/DUPLICATE LAYER (you can rename this layer when prompted but no real need)
Equalise this layer-
-IMAGE/ADJUSTMENTS/EQUALISE, you should now have a bizarre "Pop Art" looking image but the dust spots will be clearly visible-
Switch the active layer back to the background-
- In the Layers dialog box click on the "Background" layer, this should then turn blue.
The image on the screen will still be the equalised "Background Copy" layer but any editing will affect the "Background" layer.
-Select an appropriate sized and shaped clone tool(or healing brush) and go around stamping out the dust spots.
-When you think you are done you can hide the "Background Copy" layer by clicking on the "Eye" symbol to the left of the layer name.
-Equalise the "Background"layer and see if you got all the spots, if you are satisfied Undo Equalise and delete the Background copy layer.
If not satisfied Undo Equalise, Unhide the "Background Copy" layer and repeat the cloning process until happy.
* that is a safe bet because I equalised it and had a look, there is one just above the nose and likely more on your original!
If your camera sends text messages, that could explain why your photos are rubbish!

Chris's method is the best way to do it and, whilst it sounds log-winded, it only takes a few seconds to do. I do however do things slightly differently.
Before equalising I use the magic wand to select the sky and then simply equalise that. It is impossible to miss dust spots that way. Once they have been dealt with, right click, select the inverse and sharpen. That way you are simply sharpening the subject not the noise or grain in the sky. It can make a big difference if the sky is slightly noisy to not sharpen it !

Wow! You learn something new every day! So simple but I would never have thought about doing that. Cheers Mick.

I use the same method as Chris as it's very effective and has been around for a very long time in the scanning circles. I learned it years ago from a drum scanner operator.
My suggestion for the tool of choice (which has been mentioned in here) is the healing brush. The reason the healing brush is (In my opinion) more suitable to dust removal is that it only modifies the luminance of the cloned area. Dustspots are a luminance issue when you get down to it (hence why equalize makes them show up) and the healing brush is the perfect tool to take them out. This means you don't have to worry as much about the clone source, as you won't get any "clone circles" of obviously cloned areas.

Wow! I haven't tried what Mick Bajcar's quote. I should try some day.
Speaking of healing brush, sometimes I used this to remove dust spots. However, I have struggled to remove just one dust spot from one photo again again again - seem not work. So I will try Mick's
