CNSMin is an ActiveX component which you can find in ..\downloaded program files. Apparently it cannot be removed by simply deleting. 

The good news is that AdAware can get rid of the programme (042-24-09-2002 and later)

For the geeks amongst us, here is what you do.

Shut down all programmes and boot into DOS. Run the following commands:

cd DOWNLO~1
del cns*.*
del 3721\*.*
rmdir 3721
 

Restart Windows.

Then the following registry keys will need to be deleted:

HKEY_CLASSES_ROOT\CLSID\{B83FC273-3522-4CC6-92EC-75CC86678DA4}
HKEY_CLASSES_ROOT\CLSID\{D157330A-9EF3-49F8-9A67-4141AC41ADD4}
