If you wish to retain Java, then check for Updates (always listed on the forum) and delete old versions
At the last check I found Version 7 update 13 was current - Follow this if you wish to update or check your version >
1. Update your Java version here: http://www.java.com/en/download/installed.jsp
Note 1: UNCHECK any pre-checked toolbar and/or software offered with the Java update. The pre-checked toolbars/software are not part of the Java update.
Note 2: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications.
2. Now, we need to remove old Java version and its remnants...
Download JavaRa to your desktop and unzip it.
•Run JavaRa.exe (Vista and 7 users! Right click on JavaRa.exe, click Run As Administrator), pick the language of your choice and click Select. Then click Remove Older Versions.
•Accept any prompts.
