C# Dll, VB6 & MultiThreading Issues

I have C# dll called in a VB application. And this C# dll is
multithreaded, has two threads sleeping, suspended or running.
When the VB application exits I "Interrupt" and "Abort" these threads.
I think that these threads don't exit, because I see the Interop dll &
C# dll loaded in memory if viewed in the Process Viewer. More over
when I close the VB IDE, I get an error message reading "Memory could
not be read". And this error message pops up only when using the
multithreaded function in the C# dll and it does not come if we use
any other function in the C# dll.

And the question here is:
Is there any other better way to clean up after stopping threads and
also C#, VB interop?
And how can I stop this error message popping up?

Any help will be appreciated.
