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

Team Viewer is available for the Microsoft Windows, Mac OS X,[1][2] Linux, iOS,[4] Android, Windows RT, Windows Phone 8and BlackBerry operating systems. It is also possible to access a machine running TeamViewer with a web browser.[8] While the main focus of the application is remote control of computers, collaboration and presentation features are included

TeamViewer can be used without charge by non-commercial users, and Business, Premium and Corporate versions are available.

TeamViewer GmbH was founded in 2005 in Uhingen, Germany. UK-based private equity firm Permira acquired TeamViewer GmbH from Durham, North Carolina-based software developer GFI Software in 2014. The company also hosts an onlinebackup cloud service called Airbackup.

Security :

In the default configuration, TeamViewer uses one of the servers of TeamViewer.com to start the connection and the routing of traffic between the local client and the remote host machine. The software then determines how to establish a connection. In 70% of the cases, after the handshake a direct connection via UDP or TCP is established; the other connections are routed through TeamViewer GmbH's router network (via TCP or HTTP-tunneling).

Uses:

TeamViewer and similar services have been used to commit fraud via telephone calls. People are called, either at random or from a list, by criminals claiming to represent a computer support service which has identified the victim's computer as being infected by malware, sometimes using the name of a company such as Microsoft. They then ask the victim to give them access to their computer by installing a remote control service, which can allow the attacker to infect the computer with malware or to delete or copy personal files. A Wired journalist investigating the scams was asked by a scammer to install TeamViewer.
