"This file was added to my machine a few days ago and I don't know why"
How did you find or see this file? Where did it come up? What were you doing?
Something for this should show on the Startup tab:
Start> Run> type in 'msconfig' without the quotes> enter> Selective Startup> Startup tab> to expand the Command Column, hold left mouse button down on top frames of column and more to right until expanded.
Look for any process or left or Command in the next column relating to anything pcludoni> UNCHECK it> Apply> OK> Reboot
Close the nag message that comes up after checking 'don't show this message again'..
