Data Recovery Software

 Data recovery software is a program that can recover files that have been corrupted by viruses or accidently deleted. This is possible because of the way your computer deletes files. When a file is deleted, it is not completely removed from your hard drive. What happens is that a link in the system registry is removed, so that your operating system "forgets" that there's a file in that particular spot, allowing you to rewrite it with something else. Data Recovery software can then find these "lost" files and reestablish all the necessary links within your system which allow you to see and use the file
