deleting unused and unpurchased plug ins from PT 11 directory in sessions

Does anyone know how to delete from the session directory Plug ins that have never been purchased but came in on the back of another plug in? Specifically , I purchased Antares Avox 4 which comes with a variety of different plug ins that are available to purchase . Problem is that all of the plug ins are listed in the directory in sessions , even the ones that are not Ilok authorized . I would like to make it less confusing and only show the actual authorized ( working ) plug ins . I have visited Programs (x86) Anatares file on the compuetr and it shows as empty so unsure where else to look to delete unused plug ins . Anybody ?
