When your machine is idle even for a few seconds it is in fact working for the P2P network. When you install HOLA, this is what you are installing and that (above) is what it is doing. P2P can be a good thing for sharing files without the need for a huge server BUT. Most of our computers spend 90% of their processor time doing nothing and with P2P, spare processing time from member computers is aggregated in order to execute a program, share files, enable online chat and instant messaging. Peer-to-peer (P2P) networks are in use throughout the Internet.
