I just updated my Secunia PSI to the latest version (v1.0.0.1) And It is awsome. Secunia Personal software Inspector finds, assesses, and determines If security threats exist in programs Installed on your computer. It scans your computer, And directs you to vendors websites to upgrade, or install the latest patch for that software. I highly recommend this software, But who am I.
