What are the processes RBNOTIFIER.EXE and RBMONITOR.EXE ?

These processes belong to the RegistryBooster registry monitor feature. This feature performs a background scan of your system for registry discrepancies, according to a schedule specified by the user.

When invalid entries are detected by this monitor, the notifier displays a small notification of the number of entries found, just above the system tray. This notification can be clicked to open RegistryBooster in order to fix these entries.

These background processes run at low priority which means that they will not disrupt your work. By default, the schedule for the background scans is set to 'Weekly'. Although this is the recommended setting, it can be easily changed by opening RegistryBooster and going to the 'Settings' tab. From the 'Scan Settings' subsection, you can change the frequency of scheduled scans from the dropdown, or set it to 'Never' to turn the feature off completely.
