How to Disable Java in Internet Explorer (IE)
Oracle's Java scripting language has been the target of quite a few security attacks and currently (1/12/2013) it is vulnerable to a rather serious kind of attack. In fact, the United States Department of Homeland Security is warning people to disable it. So...here's how you can disable Java in the Internet Explorer browser:
Open Internet Explorer (naturally)
Click Tools at the top right. If you don't see Tools look for a button that looks like a gear (should also be at the top right)
Click "Manage Add-ons"
Scroll down to the "Oracle America, Inc" section and find the Java Plug-In Helper.
Select it and click the "Disable" button that should appear below. If it asks about disabling related plug-ins, just confirm that.
Close the Add-ons dialog box.
It may be that you'll find important
sites for you that won't work with Java disabled. If that happens,
you'll probably have to re-enable Java by following the steps above and
re-enabling. If you DON'T have a problem with sites, however, you're
probably going to be safer in the long run by just leaving Java disabled
You may even want to consider uninstalling Java from your machine entirely if you determine you don't need it.
To uninstall Java from your Windows machine go to Control Panel find "Add/Remove Programs" (or click "Uninstall a program" on newer versions of Windows) and find "Java" on the program list. Select it and click "Uninstall".
