Anyone out there able to help me on the above problem ?

I had an add in installed, i uninstalled it correctly from Excel although it
still shows up in the available add-ins list. Fortunately it doesn't show
anymore when Excel loads.

But when I download excel spreadsheets from websites which open in internet
explorer those add-ins are loaded every time.

How come, but better question - how can I really get rid off these for
always ?

Thanks,
Martin
