this file is supposed to be the Microsoft Malicious Software Removal Tool. But when i double clicked it, on the privilege escalation dialog it told me this file is from unknown publisher and the dialog window on the secure desktop is yellow, which looks like this software is not digital signed.
any suggestions?

    Hi,
    The malware signatures included in MSRT are not comprehensive.
    Try download safety scanner using the following link:
    https://learn.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download
    It has all malware signatures while Malicious Software Removal Tool has only some malwares.

    If you want to use Malicious Software Removal Tool , try download it from here:
    https://www.microsoft.com/en-us/download/details.aspx?id=9905

    Hope above information can help you.

    Did you used any download manager to download it?
    Make sure download it from:
    https://www.microsoft.com/en-us/download/details.aspx?id=9905
    Normally it will happen when it is corrupted download or downloaded from a untrusted source.
