Windows 10: Unknown program file

Hi, I have found a file amongst my Program Files and I have no idea of what it is. I am running Windows 10 Home 64 Bit on a HP Pavillion 500 series PC Model No. 500-081ea. The file is labelled as NzBiOWU5NDYy Does anybody know what it is/does and can I delete it? I have tried opening it and clicking on the applications inside but nothing happens except that my CPU usage goes sky high. The applications are labelled as:-



MmExYjg (which has a silhouette of three people and a Windows shield as a logo)


MmFiOTI ( which has a blue file and a search magnifying glass as a logo)


NTFhODA4Yz ( which also has a blue file and a search magnifying glass as a logo)



Can somebody help please?

:)

Hi,

Thank you for posting in Microsoft Community.

We understand how you feel about the situation. We're sorry for the trouble.

I suggest you to follow the below steps and check if it helps.

1) Create a new file with any extension and save it on any location.

2) Next Open Control Panel (icons view), click/tap on the default programs icon.

3) Click/tap on the Associate a file type or protocol with a program
link.

4) Either double click/tap on the file extension or protocol, or click/tap on the file extension or protocol and click/tap on the
Change Program button of the one you want to change the "current default' program association of.

5) If the program you want to associate is not listed, then click/tap on the
More Options link if available.

6) Click/tap on a listed program that you want to associate.

7) If you associated a program, then you will see this below as "Set Associations" updates and reloads.

8) Once it is done go back to the file which you have created and delete the file.

9) Go to default programs and refresh the set association programs. It should show as other unknown.

Hope this helps. Please reply to us with the status of the issue.

Are my Registry Files all legitimate programs?

Isn't there a web tool whereby I can check if programs listed in my REGISTRY FILES are legitimate programs?
