I think its installed by Q Diagnostic Engine.......

The Q Diagnostic Center provides an interesting, information-dense GUI summary of system resource usage that lets you quickly analyze system performance.

Q is composed of the Q Viewer and the Q Diagnostic Engines for Oracle and Client PCs. The Diagnostic Engine for Oracle executes on any Oracle7.2 or 7.3 database.

The Client Engine currently supports Windows 95 and NT platforms.

If u had this tool sometime it must have installed those q$views.....
