MRT.exe is the Windows Malicious Software Removal Tool. It scans for malicious files like viruses in the background and is updating itself every patch day (second Tuesday in a month).
If you have secured your system with other security tools, such as Malwarebytes, SuperAntiSpyware, Search & Destroy or Adware (Top5 Spyware Scanner for Windows 7), you may not need the MRT.exe. You can disable the Windows 7 security center completely AND delete the file MRT.exe after creating a backup.
