Most savvy computer users are aware of the need to keep their operating systems (Windows, Mac OS X) up to date. Despite applying all critical updates in Windows Update or Software Updates, many of these users place their system security and stability at risk by neglecting to apply the same measure of caution to third party applications like Mozilla Firefox and Real Player.

A few links are included below for common applications that require regular updates, but it is very important that you check all of the programs that you use for built-in updating options. It's also a good idea to make sure that you have the most recent version of the software as long as it can run on your machine. Checking the vendor's website is typically the best first step.

It can be difficult to manage updates for all of the applications we use online. The Secunia PSI is a free security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. You can download PSI from Secunia's website.
