Windows 10: What is this unknown program called 'm', published by 'C', in programs list?

Hello Microsoft community,Today I was cleaning up my laptop Dell XPS 15 running Windows 10, when I found a program listed in the control panel that I can't find elsewhere and have been unable to track down on the web so far.The program 33.5 MB has no thumbnail and is labelled simply 'm' with a publisher listed as 'C' and a version number of 3. Is this something necessary to do programming in C or is it just a junk/malware/leftover program?Sincerely,CRP.S. I attempted to upload a snipped image of the control panel readout but got an error with both png and jpg uploads.

Can't run program with 'unknown publisher'

A little background might help.

Before you run a program, it's very important to be sure that the program is actually what it claims to be. For example: Just because a file
calls itself Winword.exe, how do you know it really is Microsoft Word?

Software developers vouch for their identity by obtaining a digital certificate, which is a proof of identity not unlike a passport or a driver's license. Digital certificates are issued by trustworthy organizations called certificate authorities.

Most people wouldn't begin to know (and why should they) how to check whether a program they want to run has a valid digital certificate, so the operating system does that for you by consulting the list of known and accepted certificate authorities included
in the operating system.

So here's what happened: Windows won't open your program because the certificate authority (the 'publisher') is not, or is no longer, on the list of known and accepted certificate authorities. The publisher might have been known and accepted in an earlier
list of certificate authorities, but the lists are updated frequently. The April 2018 update, or another update, revised the list of known publishers, and the publisher for your program ain't no longer on it.

None of this was invented by Microsoft, who is simply complying with internationally accepted standards for safe computing.

You're seeing the message because Windows can no longer guarantee that the program is safe to use.

Can't run program with 'unknown publisher'

I am attempting to open a program with an unknown publisher.

Before the April 2018 update, I would see a prompt upon lunching the program that would inform me that this program had an unknown publisher. This prompt would allow me to select the 'Run Anyway' option. Since the April 2018 update, this prompt does
not display. The program does not run and does not show up in the task manager. I currently know of a workaround by disabling a feature in Windows Defender. My question is, will there be a fix for this soon?

Windows Defender Security Center -> App & Browser Control -> turn off -> Check apps and files
