P2P software opens “doors” in your computer which may compromise privacy and security. It is possible to inadvertently share private and confidential details including financial information with other file-sharers.

Some P2P programmes come with extra software, called “spyware”. This may report which websites you visit to marketing companies, or even record your passwords and send them to fraudsters.

File-sharers’ computers may be vulnerable to viruses infecting other machines on the P2P networks and to people trying to control computers remotely. In many instances remotely controlled computers are used to send unsolicited emails or spam without the knowledge of the owner.
