GFI WebMonitor makes use of the differential update system for the WebGrade Database.
This means that the whole database would need to be downloaded the first time. Subsequent updates would require only a differential update file. The size of each differential update file is relatively small, averaging less than 600 KB.
If GFI WebMonitor does not update the WebGrade database for approximately 1 week, GFI WebMonitor will automatically download the full update.
