Houston, we have a problem!

Major Tom, to Ground Control...

Remote Assistance with Windows and Macs and even newer cellphones & tablest is easy and free.  I currently use the Professional SplashTop SOS.

I also work with Google Remote Desktop, TeamViewer, Zoho, LogMeIn, GoToMyPC or Windows Remote Desktop Connection if that's more convenient for you.

For personal use, Google Remote Desktop is free.  I'm happy to help you set that up your home-to-office connection.
