What is SystemPropertiesProtection.exe???

When trying to create a system restore point prior to installing new software on my computer (Sony VGN-FW290 running on Windows Vista 64-bit home premium), I get a screen message asking for my permission to run 'SystemPropertiesProtextion.exe' from an 'unidentified publisher' asking whethter or not I should allow that program.  I have tried to find that file using the windows search engine, without success.  Should I allow the program to run?? If it is a Microsoft or Sony program, why does it show as an unidentified publisher? Is there a way to tell whether a file/program is genuinely needed to perform an operation or a 'nasty' just waiting to infect my computer.  PS: I have done a complete virus scan (404 000 files)  using ESET and no potential threats were discovered.  Ignorance is DEFINITELY not bliss!!

Well done clever person! Should I buy ProgramCheker, or is there a better solution to checking the safety/identity of a file/program?

Thank for Your good words!
If it's interesting, I'll tell it. I use online checkers of files, and send them manually if they are suspicious. And of course there are resident antiviral monitor and wall permanently running on my workstation.
And I have never tried ProgramCheker. Who knows, maybe it is good idea. I don't know. As for me, Google knows more anyway! :-)
