How to Revert to Previously Installed Content, AV, and URL Database
From the WebGUI, under Device> Dynamic updates, there is an option to click "Revert" besides the previously installed Antivirus, Applications and threat and the URL database version.
However, if newer versions of the content files are available, the previously installed version may not appear on the Web-UI. In this case, the revert operation must be executed from the CLI.
