Mining is the primary method for transaction processing, recording, and security for most digital currencies, as well as the method in which new coins are created. This is not true for every digital currency, but is central to the vast majority. We did an article which goes into more details - Bitcoin, and digital currency mining
Btw, just for clarification, I am assuming you are referring to digital currencies, and not actually virtual currencies.

It is no longer possible to mine profitably without hardware specifically made for the task. Even with that hardware the margin is very thin, and you will probably not come out ahead unless you know what your doing, don’t have any issues, and have cheap or free electricity.
If you want to try that hardware can be purchased here: Buy ASIC Bitcoin Miners & Bitcoin Mining Equipment
Perhaps if you already own the right GPU (high end AMD) and cheap power, or get the secondary benefit of heating a room that you needed to heat anyway Ethereum might still be viable to do on your PC.
