    Older versions of Sun Java have vulnerabilities that malware can use to infect your system. Virtumonde (aka Vundo) often takes advantage of these vulnerabiities.

    Please follow these steps to remove older version Java components and then get updated to the current version.

    At the time of last update to this post, the current Sun Java versions is: Sun Java Runtime Environment 7 Update 1

    Step3: Install the current version
    • Exit all browsers (including this one so read the rest or print the instructions if you cannot remember them)
    • Refer to step one and locate the file you downloaded. Double click on it and accept any license agreements and allow it to be installed.
    • Do not allow it to install any additional toolbars ( like Ask Toolbar or similar if requested ) just uncheck that option during installation
    • It take awhile for this to install so be patient. Do not run anything else while installing and keep all browsers closed while installing.
    • After installing the current version, reboot if it tells you it needs to. It does not always need this reboot so don't worry if it does not ask you to reboot.
