It appears as if you do... If so, then the message you're seeing is probably Java wanting you to update itself.. If you want to correctly update Java, then follow the instructions below:
Click on the link to Sun's Java below, then scroll down to the ''Java Platform Standard Edition JDK 6 Update 21 (JDK or JRE)'' section, then click on the "Download JRE" button. Follow the prompts, select the Windows platform and the "Language", if necessary, accept the license agreement, click the "Continue" button, then download the full ''Windows OFFLINE Installation'' file to your desktop,(about 15 MB), scan it with your antivirus (just to be sure it's clean). Once that's done, if you've already got a Sun Java version on the computer, open the Control Panel, double click on the ''Add/Remove Programs'' section, then uninstall all previous versions of the J2SE Java listed there. Once that's done, then install Java JRE 6u21 from the downloaded installer.

Once you've installed the newest version, you can disable the automatic update option from withing the Control Panel-Java icon-Update tab.
Hope this helps.
