As an application running on your computer, BigFix can automatically download and read technical support information provided by computer and software manufacturers and other technical support experts (published in the form of Fixlet® Messages) and can automatically check your computer for bugs, configuration conflicts, and security holes. When it finds a problem, it can even offer you to fix it with a simple mouse-click. Most of the time, BigFix can even alert you to a problem before any damage is done.
