How much mould do you have? If it's a few small spots, you can try scrubbing with bleach diluted with water, or distilled vinegar, or purchase a mould removing solution. It's important to note that concrete is porous. With these basic remedies, you'll only kill the mould on the surface. The mould will have roots deeper in the concrete which won't be removed, so the mould can grow back eventually.
Painting over mould will only hide the problem temporarily. Paint is porous, so the mould will continue spreading underneath the paint. You could eventually end up with a large patch of mould. You will also get unsightly air bubbles where the mould is growing, because the mould (as a living organism) releases gases.
If it's a large amount of mould, it's best to call a professional mould remediation company. You certainly don't want to scrub large amounts of mould on your own, because you will dislodge the mould spores and cause the mould to spread even faster around your home. Large amounts of mould (or even small amounts, particularly if you're allergic to it) will affect your health. Have a professional handle it.
