The Secunia Personal Software Inspector (PSI) is a free security scanner which identifies programs that are insecure and need updates. It automates the updating of the majority of these programs, making it a lot easier to maintain a secure PC. The Secunia PSI automatically detects insecure programs, downloads the required patches, and installs them accordingly without further user interaction.
The Secunia PSI also detects and notifies you of programs that cannot be automatically updated with patches and provides you with detailed instructions for updating the program when available. In most cases, you simply need to click the appropriate icon in the Results window and follow the on-screen instructions to install the latest patches.
