Oracle and the federal government has announced there is a flaw in Java and the recommendation is to disable it. However realize that you will not be able to view a number of web pages as Java is the language that some web developers use (particularly if you use the web to access information). Java is different than Javascript so pages using javascript will be fine. Firefox has an update that may have already installed on your machines that will not open Java unless it is page you request and approve opening. Oracle says they will have updates on Tuesday that will fix flaws so when you get request to update Java Tuesday do it. I would suggest at that point upgrade to latest Java.
To disable Java do the following:
Open Control Panel.
Launch the Java applet. You may need to change to Classic View (in XP) or small icons (in Vista or Windows 7).
Click the Security tab. (under older versions of Java it is the Java tab and you will un-enable all versions there)
Uncheck the box Enable Java content in the browser.
Click OK

TO SUBSCRIBE This is a little article I am doing across the Internet of my personal opinions. This reflects my personal thoughts. I try to write several times a month on a variety of subjects. It may be religious at times, political at times, and at other times just my reactions on something happening out there. It will often be like an op-ed article. If I do what I intend, you will at times want to shout I agree, other times you will want to say Dwight has really lost it now, but most importantly I want to challenge you to think. Feel free to forward this to others. If you don't want to get this e-mail let me know. Feel free to use what you read from me, but I request you give me credit and send a tear sheet if published in a newspaper or magazine. Thanks.
