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.
