Security researchers are recommending users disable Java on their computers after an exploit has been discovered that could possibly allow a malicious website to take control of your computer.
Java, a set of software tools that allows advanced features to run on websites, currently has a vulnerability that can allow an attacker to run unauthorized applications on a vulnerable computer. Being a zero-day vulnerability, antivirus firms and Oracle (the manufacturers of Java), have not had time to implement a fix, leaving both PC’s and Macs unprotected until a patch becomes available. Security firm Alien Vault as reported websites using this exploit are already showing up in the wild.
Until a patch is made available, it is recommended that users either disable Java if not required, or use a separate web browser if you do require it.
You can disable Java by following the instructions listed here. (Note you must have the latest version of Java for these instructions to work.)
The latest version of Java is available at: http://www.java.com
After review of the situation, experts in the field are estimating it could take up to two years to fully fix the problem. Therefore, TOAST.net is recommending that users simply uninstall Java. It is not really required as most webpages no longer use it extensively, and modern web browsers are able to work with those that do without the extra help.
If you don’t need Java installed on your computer (which covers 9 out of 10 of us), you can uninstall the software with these instructions: http://www.java.com/en/download/uninstall.jsp
