What to do with this Windows dot net framework message?

I ran Malwarebytes and it found 24 items, all PUP.....
I removed them, now upon bootup I get this popup.

MOM.exe   .NET Framework Initialization Error

(red X)  To run this application you must install one of the following versions of the .net framework v4.0
Contact your application publisher for instructions about obtaining the appropriate version of the .NET framework.

I can click ok or close the small window but nothing happens. Then it popups again when I bootup.

You may need to uninstall Net Framework from Programs and Settings in the control panel, then download and install the latest version from Microsoft. I believe NET Framework extends compatibility to the previous versions, try that first.

Do a system restore as well.

I would try this Tool:
Microsoft .NET Framework Repair Tool
Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

System restore did not fix the problem that started today. System restore done back to May 18th.
Did you uninstall Net Framework from Programs?
nickg5Author Commented:
no, the version on the system now is dot net v3.5

It appears that Windows is just offering the newer version.
It is not my system so I have done nothing as far as programs or settings, except I tried system restore to May 18th.
Did you try  tailoreddigital link stated you will probably have to uninstall and reinstall the .NET software.
