How often does MRT run?
How often does MRT run? MRT.exe is the Microsoft Malicious Software Removal Tool. A new version of this tool is included with the critical updates every month on Patch Tuesday (the first Tuesday of the month). It should run once -- at the time you download it -- and then be dormant for the rest of the month unless you manually start it up.
Why is MRT convenient?
Singapore's subway system or the Mass Rapid Transit (MRT) is the most convenient way for travelers to get around cheaply and easily. Hopping on the MRT lets you avoid traffic jams, though platforms can get quite crowded during the morning and evening rush hours.
