MRT application in C:\[long string of characters]

Hello!

First, please forgive me if this question/answer is located somewhere. My search on experts exchange did not yield the information I was looking for, could be that I didn't provide the correct key words to search. Please provide the link if this has already been answered, thank you!

Machine = Dell N5010 64-bit, Windows 7 Home Premium SP1
Noticed two new folders on C drive named with a long string of alphanumeric characters, for example f32763b4dd480b3dc239b032. The only content within each folder is an application named MRT.exe.

When I clicked on the folders to view contents, I was prompted with the MS User Account Control prompt to provide permissions. I clicked yes (hope I didn't screw something up by clicking yes).

I'm currently running a McAfee scan.

What is C:\[long string name]\MRT.exe? Why is this located in two different folders? Should I delete these folders? Could this be a vulnerability/security concern?

Thank you!

MRT.exe is the Windows Malicious Software Removal Tool.
The folders you describe sound like temporary download folders that probably should have got deleted after install/update.
You should be fine deleting the folders as the installed version of mrt.exe will be in c:\windows\system32.
