How safe are the files on your computer if somebody else gains access to it? If your computer is lost or stolen, or if somebody gains access to it through the internet, would somebody be able to read the files on your computer. If you have sensitive information stored such as personal details and access details for various online accounts then you would prefer it if nobody else had access to that information. This problem is particularly important for anyboday who has a laptop as these are more easily misplaced or stolen.
What you need is file protection software that employs powerful encryption technology to secure your valuable files against thieves, hackers and others. Then if somebody gains access to your computer then at least they won't be able to read your private files and possibly cause a lot more upset and misery.
