You can happily delete it if you still have it. There are many other programs called mp, as the Mail Processor, MultiPlan and many more. Of course, this is just a problem of the polluted two-letter namespace for programs and the coincidence is purely incidental and accidental. Though it's said that mp stands for Multieditor Professional, other voices relate it to 'Minimum Profit', 'Miscellaneous Pathology' and 'Meaningless Program'. Of course, there is an easter egg.
All cool programs have one.
