Did you know that your computer can become infected with malicious software simply by ‘visiting’ a website? You may not even see anything out of the ordinary while this happens because the invasive process uses software that runs in the background and can be called on by your web browser.

Java software (sometimes called JRE or JVM) is a primary example of this type of software.  In addition, even the most up-to-date version is vulnerable to attack. Many computers have Java run-time software installed, and most of those don’t even need the software in the first place.

So what you can do? Check to see if you have Java software installed on your computer

  • Visit http://javatester.org/version.html in your web browser
  • Look at what is displayed in the ‘Version and Vendor’ dialog box
    • If the box says something like ‘Missing Plugin’ you don’t have JRE installed or activated—don’t install the plugin here! You do not need to do anything other than be conscious about installing or activating Java software in the future.
    • If the box displays a vendor and version number, compare it to the current versions listed beneath the message. An example is shown below:

If Java is installed, uninstall it unless you know that you need it. You can always download a new version if you later discover that you do need it. For those who require Java, ITS recommends only activating Java in one browser and using a different browser for all other Internet browsing. For assistance with this configuration, contact the ITS Support Center at support@colby.edu or ext. 4222.

  • Uninstall Java Software
    • On Windows Computers, this is done through Add/Remove Programs:
      • Click the Start/Windows button, open the Control Panel, and select ‘Add or Remove Programs’ or ‘Uninstall a Program’
    • Uninstall any Java software found in the program list (there may be more than one version installed, so make sure to get each one)
      • On Apple/Mac computers, Java can be centrally enabled or disabled through the ‘Java Preferences’ application, located in the /Applications/Utilities folder.
      • Installing a current Java version (Windows computers only)
      • Once Java has been uninstalled, visit http://java.com/en/download/index.jsp to obtain the latest version.
