Old versions of SunJava (up to JRE 6 Update 7) have been preserved when installing updates and should be removed, as older versions of SunJava are very vulnerable to Winfixer/Vundo. It took from 2005 until the JRE 6 Update 10 update for SunMicrosystems on Sun Microsystems to get the SunJava autoupdater to uninstall earlier (vulnerable) versions of the program. Updates for JRE 6 Update 10 forward are in a separate jre6 folder, which is overwritten when a new JRE is installed. Even if you use the latest version of SunJava, it is vulnerable to infection if older and vulnerable versions are still present on your computer. Unfortunately, simply using Add/Remove programs to uninstall older versions is not completely effective.

We recommend that you try JavaRa. After upgrading Java to the latest version today, I launched JavaRa and used it to remove older versions of Java.

Two old versions were found on my computer, which I then removed.

NOTE My colleague MVP and TWCF Mod Corrine adds: JavaRa has not been updated to support deleting JRE 7 and seems to have problems with JRE 6u32. He moved to SingularLabs.com. Besides, Paul McLain no longer supports JavaRa, but Freð ðe Vries still does.
