Introduction

File sharing programs came to worldwide prominance with the release of Napster in 1999. Napster was created by Shawn Parker. Napster allowed people to share files over the Internet. Since then a host of other file sharing programs have been released, which also allow users to exchange files, such as images, media files and other data. Napster was a small program that only allowed users to download a selection of file types, with later programs such as audiogalaxy and kazaa allowing users to exchange a larger variety of files.

One of the chief problems that users have experienced with file sharing programs is adware/spyware. Some of the most notable file sharing companies have secretly installed adware/spyware programs with the installation of the main file sharing program. Viruses are another problem area, with many downloaded files including them. The developers of file sharing programs have taken note. Most promise they are now adware/spyware free, and have facilities to scan every downloaded file for viruses.

A controversial aspect of file sharing is piracy. There has been a crackdown on illegal file sharing by media bodies such as the 'Recording Industry Association of America'. They have correctly cited that downloading and uploading copyrighted materials without permission, violates international copyright infringement laws. Many users, especially in the US, have been take to court or have settled out of court for fines of over $2000.

It should be highlighted that file sharing / peer to peer sharing programs have a perfectly legel use. Sharing files which are not copyrighted is within the law. It is only when copyrighted files are uploaded and downloaded, without the express permission of the owner, that the use of such programs becomes illegel.
