One of the more popular ways to fix computers these days for people and customers is by doing it remotely. This can be a difficult task for the everyday average computer user. Also some of these services will cost you some money. CrossLoop has developed a free secure screen sharing utility designed for all technical skill levels. This all can be done without changing any firewall or router settings. 

There is no reason to worry about security either. All section data is encrypted at the end-points before being sent using a 128-bit encryption algorithm using a randomly generated 12-digit access code. When any screen images are being sent to a remote computer there will need to be explicit permission.
