Norton Ghost program enables you to save an image of you PC onto a spare partition. Then if you feel you require to Format and reinstall everything due to a fault or virus....you just reinstall the Ghost Image you saved and in 10 minutes your PC is back to normal before the problem...It save hours of work having to reinstall everything.

I set up my Windows OS plus a small selection of essential programs.
I reinstall my saved Ghost Image back every 2 to 3 months for a clean start again. I have used it for years and its very reliable.
