"(Reuters) - The U.S. Department of Homeland Security urged computer users to disable Oracle Corp's Java software, amplifying security experts' prior warnings to hundreds of millions of consumers and businesses that use it to surf the Web.
"We are currently unaware of a practical solution to this problem," the Department of Homeland Security's Computer Emergency Readiness Team said in a posting on its website late on Thursday.
"This and previous Java vulnerabilities have been widely targeted by attackers, and new Java vulnerabilities are likely to be discovered," the agency said. "To defend against this and future Java vulnerabilities, disable Java in Web browsers."
I only use Firefox so I can't tell you how to disable Java on any other platform, but in Firefox click on Tools, then Ad ons, then go to Plugins. Look and see if you have Java or Java tools. If you do click on Disable and close your tab.
