An exploit in the popular cross-platform Java programming language has been discovered, and the only way to avoid it right now is to either disable Java in each of the browsers you use, or even better, uninstall it entirely from your PC or Mac if you don’t have a critical need for it. Personally, at this point, we’re not using Java in our office much, so we’ve simply uninstalled it for now.
To uninstall in Windows 7:
- Go to your Control Panel and select “Uninstall a program.”
NOTE: Other versions of Windows will have different wording for this choice. (And, by the way, if you’re still using Windows XP or earlier, it might be time to upgrade to Windows 7 – or a new PC with Windows 7 or 8 on it. This will also help you avoid problems with viruses and other exploits.)
- Find items that include “Java” in the list of programs.
- Uninstall all versions of Java on your computer. There may be more than one. Java is notorious for leaving old versions behind when it updates, though this has been less of a problem recently.
- Close the Control Panel. Restarting your PC isn’t a bad idea at this point to kill any background stuff that might have been using Java.
The Next Web has a good article with more details on the exploit itself.
