RunDll error

Hello.,
My HP machine with Windows Vista Premium, started giving these two errors
everytime I logged in, error #1:
Rundll error:
Error loading C:\users\joe\AppData\Local\Temp\urqrr.dll
The Specified module could not be found.
Error #2:
Rundll error:
Error loading C:\users\joe\AppData\Local\Temp\lifeb.dll
The Specified module could not be found.

I ran msconfig and I see that the lifeb.dll is an start up item for
MSserver, if I disable it, the driver for my network card won't work.
The urqrr.dll I believed has to do with the sound card.

Anybody can help with this?

thanks,
Jose G.
