Question : not a valid Windows image

I keep getting the error:

The application or DLL C:\Windows\system32\nasotive.dll is not a valid Windows image. Please check this against your installation diskette.

It pops up everytime I open an application.  Is there a way to stop this?

Answer : not a valid Windows image

Nasotive.dll is a malware..

I suggest removing it with spybot search and destroy..
