The Department of Homeland Security has warned users to temporarily disable Java software to avoid a cyber attack on their computers. The Department of Homeland Security’s Computer Emergency Readiness Team issued a vulnerability notice:
“to address a vulnerability in Oracle Java Runtime Environment (JRE) 7 and earlier that is currently being exploited in the wild. This vulnerability may allow an attacker to execute arbitrary code on vulnerable systems.”
To find out which version of Java your computer is running, go to www.java.comand click on “Do I have Java?” That brings up the Verify Version of Java screen. Click on the Verify box and it will tell you which version of Java you are using.
If you have Java 7, the easiest way to disable it is to make sure you have Update 10 and you are not using Internet Explorer. If you do not have Update 10 but have Java 7, upgrade to Update 10. This will allow you to more easily disable the program than if you have previous Updates.
