Disable Java to protect your computer


Few of my friends are very active in Google+. They are always fond of browsing trending topics on Google plus. On 10th of January #java was a trending on Google plus. Slowly it was flooded with messages regarding java 0 day exploit!

A Google plus post from thenextweb.com addressed the only solution suggested by The US Computer Emergency Readiness Team (US-CERT) was to disable java to save your computer from possible threats.

Java is one of the most popular programming language that enables programmers to write applications that may run on any device. Billions of mobile phones and desktops run java. Java powers our set top boxes, web cams, blue-ray players, games and many more systems. A message to disable such highly used and powerful tool came as a BIG shock!

You might be thinking that “How this message can affect you?

Java is also used with internet browsers that we use every day! Java 7 update has vulnerabilities that may allow any hacker to install and run arbitrary code on your computer without your permission. Such malicious code may steal your passwords, financial information etc. All these can be done simply when you are browsing internet and visiting websites!

Actually you don’t need java all the time when browsing internet!

So, let’s see how to disable java from your Google Chrome browser. From top right corner of your Google Chrome select Settings.
