With an incredible range of uses, Team Viewer allows you to share what's happening in the world of your computer screen with those around you.
An intuitive array of features such as remote access and file sharing help to pad out the awesome which this provides.
On login you are given an access code and a password which are unique to your computer and you can use the web-based version to access your system from a public computer.
The rights and access are customisable and ensure you can have just what you want and keep yourself and your set-up protected. There's even VoIP-audio/video for direct or in-conference communication.
