Keep Your Operating System Up To Date
Operating systems, like Windows XP and Macintosh OS X, are made up of countless parts with different functions ideally working in harmony. That some of these parts should be less than perfect is inevitable. But when a problem leaves a hole in your machine's defenses, it is extremely important to patch it as soon as possible. This is best accomplished by using built-in automatic update features through the Windows Security Center in Windows XP, Automatic Updates control panel in earlier versions of Windows, and the Software Update application in Macintosh OS X under System Properties. Keep in mind that your machine may need to be restarted after you update.
