A Java update released on 10/10 was reported in the posting Java Update Clobbers 29 Security Flaws. This posting tells you how to update your installed version to the current Java 6 Update 22. Your installation may update automatically if you have it set up to do so. I recommend checking and updating it right away. I also concur with Brian's suggestion to avoid the extras that want to install themselves when updating Java. Don't rush through the installation screens without looking for the optional extras that require you to "opt out".
On Windows PCs Java is not loaded until needed to run a Java applet, such as the popular addonChat used by my ham radio friends. When loaded, you will see a Java icon in the tool tray.
If you want to make sure that Java (and other programs) are updated on a timely manner to avoid security flaws, you can choose one of the following tools that are also mentioned in Brian's first posting mentioned above:
- FileHippo Update Checker
- Secunia Vulnerability Management Tools
- Secunia Personal Software Inspector
- Secunia Online Software Inspector
I use the Secunia Personal Software Inspector continuously, and run the File Hippo tool occasionally.
