How to remove old and redundant versions of the Java Runtime Environment (JRE)?

Java Runtime Environment (JRE) allows you to run applications called ‘applets’ that are written in the Java programming language. You probably have JRE installed on your computer because these applets allow you to play online games, chat with people around the world, view images in 3D, as well as many others.As with all software, the JRE is updated on a regular basis. Updates are necessary to add new functionalities, to remove programming bugs or to repair possible vulnerabilities. Usually older versions of programs are removed during the install of new versions but Sun (the owner of Java) has somehow decided not to do this. The result is that a number of different versions of the JRE may exist on your computer. These older versions potentially pose a threat to your sense of security due to the possible vulnerabilities or security holes that may exist in them.
JavaRa is a small freeware (34Kb) that check if your computer has the latest version of Java Runtime Environment (JRE). If the version you have installed has been superseded by a newer version the program will download and install this newer version for you, by running Java’s update program. JavaRa then allows you to remove all possible older versions of this program.
This will ensure that the security of your computer is enhanced and extra space on your hard disk is created.
Currently, JavaRa supports Windows 9x, 2k, XP, and Vista without UAC.

  1. Great post!

    It is very important to remove those older versions.

    Too many people end up with the very nasty and sometimes difficult to remove Virtumundo/WinFixer malware on their pc because it exploits a vulnerability in an old version of Java in order to install itself.

    If you have ever been infected with Virtumundo/WinFixer in the past, now you know how it got there and what you have to do to prevent it from happening again.

    Uninstall all those older versions as soon as possible!

  2. Very nice program. It's quite useful to me
