runsrv32.exe, what is it?

I've got this dos window that pops up when I start my computer. In the
window header, it says the process name is runsrv32.exe. A brief web
search has revealed that this is some sort of virus or spyware.

What is runsrv32.exe?
What does it do to my computer?
How do I get rid of it?


Thanks for the help,
Don
