Stay Secure with Secunia Personal Software Inspector

The Secunia Personal Software Inspector (or PSI in short) is a free security tool designed to detect and update vulnerable and outdated programs and plug-ins installed on your computer which expose your PC to attacks. These type of attacks attacks which exploit vulnerable programs and plug-ins are rarely blocked by traditional anti-virus software and are therefore increasingly used by cyber-criminals.

The only solution to block these kind of attacks is to apply regular security updates, commonly referred to as patches. Patches are offered free-of-charge by most software vendors, however, finding all these patches is a tedious and time consuming task. Secunia PSI automates this and alerts you when your programs and plug-ins require updating to stay secure. It not only tells about the usual updates for Microsoft Windows but every single program found on your computer.

You can download the free Secunia PSI tool from http://secunia.com/PSISetup.exe. The download is in form of a setup file which you have to install. The download file is merely 1.7 MB in size and takes only a few seconds to download. Once you have downloaded, double-click on PSISetup.exe to install it.

After the installation is over you can run Secunia PSI by running it from its Start Menu shortcut. You need an active internet connection for Secunia PSI to work as it checks its database located at its servers.

A green rating means program is updated and secure. A red rating means that program is very insecure and you should immediately update it.
