Teamviewer (Free)
Ever had family call you for tech support in the middle of the day, and home is far away? For those of you who have to play family techie, check out TeamViewer. This app provides you with an easy and secure way to remotely access Windows, Mac and Linux systems. Once you have access, you can use it to troubleshoot some computer problems (OS has to be working though) without needing to be on-site.
