Take the case of the Chrome web browser which, according to Google itself, has been found susceptible to five new security vulnerabilities. While Google has issued a security update for Chrome users across the Windows, Mac and Linux platforms, with Android no doubt soon to follow, simply sitting back and waiting for this to roll out is not advised. But even if you take action to kickstart the update process right now, you still wont be protected from attack unless you do one extremely important thing.

Simply heading for the About option in your Chrome browser settings to check for, and start, the update process is not, however, the one critical thing you need to ensure you do to stay safe. Rather, what Im referring to here is hitting the relaunch button once the download and install have completed. This is required in order to enable the update and get that protection working for you.
