TeamViewer - текущая сборка эффективной утилиты для получения доступа к удаленному ПК, в
 которой осуществим обход файрволлов и NAT прокси. Средство даёт возможность получить доступ
 к компьютеру из любой точки интернета (IP-адрес удаленной машины можно не знать, но на втором
 комьютере тоже должна быть эта программа). Крoме доступа к рабoчему столу и управления
 удаленным кoмпютером, можно передавать файлы, устраивать презентации, пoмогать настроить
 компьютер, oбщаться в чате и т.д.

Features of TeamViewer:

Remote Control without Installation:
· With TeamViewer you can remotely control any PC anywhere on the Internet. No installation is
 required, just run the application on both sides and connect - even through tight firewalls.
Remote Presentation of Products, Solutions and Services:
· The second TeamViewer mode allows you to present your desktop to a partner. Show your demos,
 products and presentations over the Internet within seconds - live from your screen.
File Transfer:
· TeamViewer comes with integrated file transfer that allows you to copy files and folders from
 and to a remote partner - which also works behind firewalls
Works behind Firewalls:
· The major difficulties in using remote control software are firewalls and blocked ports, as
 well as NAT routing for local IP addresses.
· If you use TeamViewer you don't have to worry about firewalls: TeamViewer will find a route
 to your partner.
Highest Security Standard:
· TeamViewer is a very secure solution. The commercial TeamViewer versions feature completely
 secure data channels with key exchange and RC4 session encoding, the same security standard
 used by https/SSL.
No Installation Required:
· To install TeamViewer no admin rights are required. Just run the software and off you go...
High Performance:
· Optimized for connections over LANs AND the Internet, TeamViewer features automatic
 bandwidth-based quality selection for optimized use on any connection.
