It’s Time to Disable Java on Your Computer

Want to safeguard your computer from hackers? Slate technology writer Will Oremus has one idea: disable Java. If you do not know, Java is software that runs interactive functions on some webpages. The software has been roundly criticized for being an open door of sorts to hackers. In a recent story, for example, Business Insider pointed to the 700,000 Apple computers contaminated earlier this year with the Flashback Trojan malware. All of these computers were running out-of-date versions of add-ons that let their web browsers run Java. The simplest way, then, to protect your computer? Oremus says it is all about disabling Java.

Security flaw

In an earlier version of Java there was a security flaw that hackers took advantage of. Luckily, Oracle quickly honed in on the issue and fixed it in a recent version, but not before the damage was done. The lingering problem is that if you still have an old version you may be vulnerable. The best option is to disable it. This is not a big deal as most websites do not require Java anymore to work.

Turning off Java

Turning off Java requires different steps depending upon what web browser you use. In Firefox users must first select “tools” from their browser’s main menu. They should then click “add-ons” and the disable buttons next to any Java plug-ins.

Safari users must first click “Safari” in the main menu bar and then “Preferences.” Once they’ve done this, they can select the “security” tab and make sure that the button next to “enable Java” is not checked.

Google Chrome users need to type “Chrome://Plugins” in their browser’s address bar. They can then click the “disable” button listed below any Java plug-ins.

Don’t touch JavaScript

One thing you must keep in mind when you go to disable Java is that Java and Javascript are very different things. Most websites use Javascript, so be sure that you do not disable it accidentally.
