unknown dll file

I have a Dell PC with Win XP Home installed. I keep getting a rundll error that says:

“Error loading c:\windows\system32\ktjoprso.dll
The specified module could not be found.”

So far, I have tried MS Knowledgebase and Google and can find no information on this dll file.
Is it part of a virus or malware?
