Ever since I took my Canon EOS 20D in for a cleaning all my pictures, when set in auto mode, are really dark, even in bright sunlight. I am new to photography and have no idea what could cause this problem.

i suggest you take the camera to a digital Canon repair shop and ask them for a repair quote. They may charge for a quote unless you go ahead with the repair, then you can decide whether to get a new body or get it repaired.
You didn't say which shooting mode you're using, but I'd bet you're in Manual mode and have dialed in a completely wrong aperture/shutter speed combination for bright lighting conditions. For example, 1/60th of a second and f2.8 in bright sunlight would be "burning out" your image, so the camera may be giving you an error message. Try using AUTO or PROG setting and see if the problem persists. If it does, try a different lens. You may have an incompatible mount, or one of the contacts may be damaged. If all else fails, try your lens on another Canon camera.
It sounds like the aperture is getting set very high. If the aperture is a high number, the lens opening is very small which lets less light in and would cause a dark image. This would also show any dust that is in or on the lens or image sensor. The dust doesn't usually show on apertures with a larger opening (smaller number). Make sure your aperture is being set to a reasonable number, probably no higher than 8 or so.
The autofocus mechanism on some lenses can be damaged if you manually focus while the camera is attempting to autofocus. Basically, you would be working against the motor and gears.
There is no need to download software before using the camera, however, I would suggest going to Canon's website and downloading the firmware upgrades for it. Here's the link:

Hope this helps!
If the camera is working properly with other lenses, then you have a problem with that lens. In M, you can set the aperture yourself, and the photos come out properly exposed. When the lens is set to auto, apparently it is going to minimum aperture and not responding to the camera's 'instructions'. The thing that makes me think so is that you say everything looks dark through the optical viewfinder. Normally the aperture stays full open so you can see and compose your shot, and only stops down to the correct aperture when you actually take the shot. I would suggest having the lens checked by an appropriate camera service shop.
I had the same problem before. Did you check to make sure your exposure compensation wasn't set at a negative number? half press the shutter and rotate the large dial on the back of the camera to change the exposure to 0. If this just changes your auto focus points, you have to change your custom function 13 from a value of 2 to 0 and then try half pressing the shutter and rotating the large dial in the back again. This fixed my problem with shooting in P mode (which I only used when absolutely necessary) and I hope it helps you.
