Notes about the RFB file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The RFB file type is primarily associated with 'RoboForm' by Siber Systems Inc.. RoboForm is a password manager. It remembers passwords, logs you into Web sites and fills forms with one-click.
