Definition: ActiveX is a proprietary addon to Javascript provided by Microsoft in the various versions of Internet Explorer. Its purpose is to allow those companies using IE for their intranet to allow Javascript to access information from the computer itself. Microsoft recommend that anyone running Internet Explorer on the internet have activeX turned off since web pages do not know how your computer is configured and such access can lead to major problems with viruses and spyware.
