Trend Micro recommends manually updating your components immediately after installing PortalProtect or whenever there is a virus outbreak. This establishes a baseline of security for your SharePoint environment.
If you are updating components for the first time, be sure to select the Download Source before updating.
On the left menu, click Updates > Manual. The Manual Update screen appears.
Select the check box(es) of the component(s) you want to update.
Click Update. PortalProtect begins updating.
Click Reset to change all download source settings to their default values.
