Some camera makers do default to a slow shutter speed in order to fill in the background when shooting flash.

Your camera has a full set of manual controls.
When shooting with flash:
Switch to "Shutter Priority" and set your shutter speed to about 1/100th of a second.

Try a test shot.
If the result is not well lit, raise the ISO setting to 100 and shoot another test shot at 1/100th of a second.

The ISO can also be set to 200 or 400.
ISO is equal to using a higher speed film in a film camera.
The higher ISO settings can result in more noise in the dark areas of the photo. In the film world, noise is the same as grain when using high speed film.

Digital SLR cameras do better in low light situations.
For several reasons:

1.
You can use a faster (brighter) lens.
i.e Canon has a 50mm f1.8 lens that sells for about $80.
When this lens is used on a DSLR, it performs as a 80mm lens (due to the size of the DSLR image sensor).

2.
You can raise the ISO as high as 1600 with little noise due to the fact that DSLR cameras have a larger image sensor.

3.
The built in flash is much more powerful.
