Lol, the OP installed a program that came with the keylogger/spyware application msdcsc.exe. It wants you to uninstall Google Chrome and use Mozilla Firefox because it doesn't know how to spy on Google Chrome's data yet.
Go and install an antivirus program like AVG or Avira, run the antivirus program and it should delete msdcsc.exe from your C drive.
