This icon is the Automatic Updates icon which appears in the System Tray (the lower right corner of the screen) whenever there are new critical security or software updates that you need to install on your computer.

When your computer detects that a new update is available to download and install, the following speech bubble will appear in the lower right corner of your screen stating: New Updates are ready to install.

Note: You may need to restart your computer after installing the updates, so remember to save your work. If you choose to install the updates at a later time, you may close the speech bubble and double-click on the icon at any time to have it prompt you about the updates.

When you are ready to install the updates, double-click on the Automatic Updates icon in the System Tray.

In the automatic Updates Ready to Install window, read about the updates by clicking on the Details button and then click Install after installation is complete. If you are asked to restart your computer, click Yes.
