ICQ Pro is a program that lets you find your friends and associates online in real time. You can create a Contact List containing only people you want to have there, you can send them messages, chat with them, send files, configure ICQ to work with external applications and more.
Note: ICQ Pro is the new name for the original ICQ, as ICQ Lite is now also available.
