    Mpsigstub - What is it?

    Hello all,

    I have a folder under root C which is named a random selection of letters & numbers. In that folder is a file called Mpsigstub.exe? Looks like it appeared back in 2015.

    I right clicked properties and there's no name saying who its from?

    What is it?
    Should I delete it?

    MPSigStub.exe Windows process - What is it?

    - note the locations mentioned, which seem non-specific

    You could send yours to Virustotal for analysis (just search for Virustotal)

    It's even possible it's something left over from a previous version of Windows from which you upgraded, if you did that.

    However lacking info in the Details fields sounds odd.

    Yes I did upgrade from W7 to W10.

    Tried to upload the file to virustotal but the file would not open (ie upload).?
    Tried to delete via Windows Explorer, but it says I need Administrator permission. But I am the administrator?

    Any other ideas on how to delete?

    You can delete pretty much anything if
    - you use Emco MoveonBoot (also restarts to delete) - free
    - you use FileAssassin - free
    - you boot to either
    - an offline command prompt (eg. via SHIFT + left click restart etc
    - a live boot disk such as Kyhi's from the top of the Software and Apps section here (or even a Windows bootable medium and via Repair Your PC to a command prompt)
