1\. Select the **Control Grid** tab on the top menu bar.
2\. Navigate to the **Anti-Virus** tab.

4\. Click the green **UPGRADE** button (**OR** the **UPGRADE ANTI-VIRUS** button if upgrading multiple computers via the Action Toolbar).
5\. A prompt will appear to inform you that a reboot will be required and that any unsaved work will be lost. Click **UPGRADE**.
6\. The Upgrade will now be performed, and the Installation Status will update.
