Secunia Personal Software Inspector 3.0 Beta

QUOTE: Secunia’s Personal Software Inspector (PSI) identifies out-of-date applications and helps you get updates. At the 2012 RSA Conference Secunia announced the beta release of version 3.0, which radically simplifies the process. The purpose of the product is to keep users’ systems safe by making sure all security patches are applied.  Where version 2.0 could only automate installation if the vendor supplied an interaction free script, version 3.0 includes technology to “wrap” the installation process for any update.
