Software

The software on your computer is often an overlooked security risk. A security flaw or vulnerability in software need only be exploited once to open up the personal information contained on your computer.

Some popular programs, particularly free Internet applications and file-sharing programs, require installation of additional programs from other companies.

Here are some steps you can take to protect yourself against the risks inherent in installing software on your computer.

• Don't install unknown software. Before installing any program, make sure you know what it does and how it will affect your computer.
• Be wary of file-sharing programs. These programs open up your computer to many other people by providing access to particular directories in your computer. Before installing any type of file-sharing program, learn how to properly configure the software to decrease the chances of a security problem.
• Use spyware detection software. Such software is designed to find and remove hidden or intrusive software and should be run every week or so. To learn more, search for Spyware and Adware on Google or other search engines.
• Use only the newest version of your browser. Each browser release updates standards and fixes security holes present in earlier versions. If you have the newest version of your browser, you should also check the publisher's web site to see if security or other patches are available.
