Malicious Software Removal Tool in Win10 Home won't run

Anonymous

I am running Windows 10 Home 64bit. I used to run the Malicious Software Removal Tool, but, all of a sudden, it doesn't run any more.

I've downloaded the most up to date version available from the MS website.

I've tried running it as Admin as well.

But, the tool just doesn't run.

Any ideas, please?

    Hi,

    If you have not yet done so, in file explorer navigate to Windows >System 32 >MRT.exe then right-click on MRT.exe and select properties. In the General tab make sure that the Read only checkbox is clear. In the security tab you can check what the permissions settings are for your account.

    Hello Rob Koch,

    Excellent post Rob.  Thank you for your contribution. 

    We are stuck at this point in time.... RikDatta, is unable to execute a MRT scan in the run box.  He was previously able to do this.  A message is prompted "System Administrator has blocked this app from running" ...but RikDatta is the Administrator of his computer.

    We have tried some strategies all unsuccessful so far.  Any suggestions?

    Regards,

    Wayne

    Great write-up Rob, very thorough and informative.

    This confirms what I had suspected was the case concerning the files infected counter showing that X number of files had been detected as the scan was in progress but then the end result of the scan was "No infection found."

    As a point of interest, below is a copy of the log entry for the full MSRT scan that I had run and was referring to in my previous reply on June 12th. (This scan had shown a count of 10 files infected at approximately the 75% point of the scan).

    That's very kind of you, Wayne.

    For one moment, I thought that the issue had resolved itself.

    I look forward to anything you may find.

    Cheers.

    Rik.

    RikDatta,

    I understand that we are back to square one and that the MRT will still not execute from your run box.

    I'm still thinking the solution is to be found in Martin Brinkmann's article below.....but I must research it further before any more comment.

    I'll get back to you when I find a potential solution.

    Regards,

    Wayne
