Program to help you to keep your software up to date.
Secunia PSI is a program, which checks if the installed software on your computer is up to date. It also offers you links straight to the vendor's homepage to fix software that is not up to date. You get Secunia PSI here : Secunia PSI
Just download the file and save it to your computer. Then doubleclick it and start the installation wizard. It is a program you install so it should go on the system drive of your computer (as opposed to the data drive). An image will be taken of this drive so that we can quickly retrieve it if we have to.
After you have installed the program, you just have to start it and hit the "Start Scan" button. Then Secunia PSI will scan your system and if necessary tell you which software you have to update!
To fix the listed software problem you just have to click the "Solution" button and Secunia PSI will either directly download the needed update or take you to a page where you can download the update. If you are more adventurous you can switch in the upper panel to the "ADVANCED" mode. Here Secunia PSI will even look deeper into your system software and tell you which programs are considered to be possible security leaks.... but in the ADVANCED mode the fixing is somehow trickier: You have to download the software yourself, delete older versions and put the new patch in... so its not a "one click" solution any more, but I guess that is why it is called advanced
To update the software just click the "Insecure" or "End-of-Life" words and it will take you to another Secunia PSI page, where you can actually view the insecure programs.
In the lower left corner of the above software screen you see the version number of Secunia PSI you are currently running (in the image it is version 126.96.36.199). It will notify you, when you can download a newer version from the secunia website.
