Very suspicious update popups on Windows 10

I have been getting a strange popup for update without any update about what it's about.
It also want's to install Yahoo search

It has happened few times so far and I am unable to figure out which program is it related to.

I used process explorer and to find out that it's mshta.exe - but not anything more than that.

Could anyone suggest what it could be?

I am attaching a screenshot for your reference

Thanks Dencal for your reply.
Could you please explain what those commands do?

Thanks again Dencal.
Does the issue look like a corrupted registry related issue?
Have you come across such issues before?
It would be helpful if you could give some more information about it.

takias,

Check you system with Malwarebytes (install free version) and ADWcleaner. That update window doesn't look good to me. Don't know nothing about any Yahoo software, but if you can, get rid of it.

Edit: here is one similar user report on reddit

I, too, suspect you have a virus. It is most likely the Chromium Browser virus/malware.

@takias, this is known malware and has come up before on this forum...
Can't find the source of this weird update dialogue

Thanks a lot AndreTen , philc43 and Bree for support and the links.

I ran ADWcleaner and that seems to have have resolved the issue! :)
Let's see.
