Google Chrome is the most popular Web browser around, and if you're one of the many people who uses it, there's an update you need. It includes patches that fix four security bugs discovered by outside researchers.
The issues are all listed as medium to high severity by Google, so it's important that you download this update as soon as possible.

Your Chrome browser should update automatically when it detects a new version is available. However, with an update this important you don't want to take chances; you need to double-check.
Open Chrome and in the upper-right corner click the icon with three horizontal lines. Then select "About Google Chrome."
Look at the string of numbers where it says "Version." It should reflect the latest version "43.0.2357.130". It if doesn't, Chrome should automatically start checking for and installing the update. Once the update is installed, click "Relaunch" to restart the browser.
Of course, there's another way to tell if there's an update waiting. Chrome normally updates when you close and open the browser. If you keep the browser open all the time, it doesn't get that chance.
That's when you'll see the icon with the horizontal lines in the upper right corner start to change color. If you see green, that means an update has been available for two days. Orange means it's been waiting for four days, and red means seven or more days.
