Peer-to-peer (P2P) websites are fraught with risk. To share files, like games and music, through a peer-to-peer (P2P) network, you download software that connects your computer to other computers running the same software – sometimes giving access to millions of computers at a time. This has a number of risks. You could mistakenly download malware, pirated or copyrighted material, or pornography, or allow strangers to access and share your personal files. Best not to visit P2P sites to begin with.
