Filesharing tools increase the risk of malware infections and can also facilitate the sharing of more data than may be initially intended.
Filesharing tools, such as eMule and Bittorrent, are used to download music, movies and software from other users in that network. Most of these protocols are illegal to use due to the sharing of copyright-protected material. About 60% of the software found in the most popular P2P networks has malware attached to it; unfortunately, users are typically unaware of this risk. Even the software used for sharing files may present a risk, as they are frequently not secure. The sharing of unwanted directories is also common.
