What is the best solution for remote desktop / visual support? [closed]

Question

We are currently investigating different remote-desktop support solutions to help our clients if they have any problems with our software and I would like some input on the best solutions out there.

We have the following needs / wishes:

• Cross platform
• Preferrably no installation on the user-end
• Should penetrate firewalls and not be bothered by antivirus stuff.
• Should leave no residu behind after support.

I know of VNC, logmeinrescue.com, dameware remote control, msn remote desktop and many others, but which one is the best?

Answer 1

I would also suggest TeamViewer, there is a free version and a commercial one that you can rebrand with your logo to redistribute to your clients. It does require (non administrative) install but works also behind firewalls.
