TeamViewer is the premier software solution for remote support, remote access, and online collaboration.
How secure is TeamViewer?
All TeamViewer versions use full encryption. Encryption is based on 2048bit RSA private/public key exchange and 256 Bit AES session encoding. This uses the same security level as https/SSL and is considered completely safe by today’s standards. The key exchange also guarantees that the data transfer  is completely encoded from client to client and that any routers or servers in between (including TeamViewer Servers and Routers) are unable to read or analyze the data stream.
TeamViewer is offered free of charge to everybody for personal, non-commercial use
