Team Viewer 

 Team Viewer is a proprietary computer software package for remote control,online meetings, web conferencing and file transfer between computers.

Team Viewer may be installed with an installation procedure, although the 'Quick Support' version will run without installation.To connect to another computer, Team Viewer has to be running on both machines. To install Team Viewer, administrator process is required, but once installed it can be run by any user. When Team Viewer is started on a computer, it generates a partner ID and password (user-defined passwords are also supported). To establish a connection between a local client and a remote client, Team Viewer generated ID and password of either client are required. The local client requires the remote client's ID and password to gain control over the remote client, whereas the remote client requires the local client's ID and password to gain control over the local client.
