The Firefox web browser does a great job of alerting you when there are critical updates available. But how about the dozens or hundreds of other programs you've installed on your computer?

Software security firm Secunia's Personal Software Inspector (PSI) is a free application that alerts you when updates are available for your programs.

When you install PSI it will scan your computer for installed software and categorize each program as up-to-date, insecure, or end-of-life. The program has information on more than 4,200 commonly used applications. Whenever a software maker pushes out a patch or an update, PSI will notify you and provide a download link.
