Don't mind what it was. Most likely it was malware and you should be glad it's gone.
Now run msconfig, go to the startup tab and uncheck the line telling Windows to run it at startup. Then the message will be gone also.
Im using windows 7 home premium, every time my pc starts the windows this massage will show up "there was a problem starting msihuu32.dll. The specified module could not be found"
Any help? plsss...
