Hi I am planning to buy a software which can enables you to restore your computer to a specific earlier restoration point. I see this function as a great way to reduce the number of infected computers in my home and I see it being used in most of the cyber cafes. However so far I've only come across Norton Ghost software which has this functions and am here to see what other softwares are there before paying for it.

A good freeware alternative to Norton Ghost !

If you need commercial paid software, you can try Rollback RX which seems to be the best paid alternative for Goback. It works with Vista too...
