Adware/Unwanted Application Removal Help

[PreVet_LC]

Hey yall! Ok, to start off I've got an HP Envy that runs on Windows 11. 

For the past at least two months, I have been getting this notification telling me that I have a "Critical PC Registry Issue" that I need to fix using some iolo System Mechanic software that I do not want. I originally thought it was a legitimate HP notification, but now looking back, that was stupid cause it's not. 

Today, I investigated the notification and found it was coming from something called "HP Recommends". I found some application on my computer that I uninstalled it thinking I got rid of it, but it just changed names to "System Notifications". 
I am at my wits end trying to figure out what the source of the notification is. Has anyone else had this problem and successfully gotten rid of the problem? I found another thread with someone who has the same notification I am getting, but it looks like they were encouraged to fix the "registry issue" instead of deleting the adware. Here is the link to the thread and the image of the notification received (not mine, but again, the same one). Critical Registry Error - HP Support Community - 9299405

I have seen other posts concerning that particular software.  Here is one:

Notice that the last post in that thread.  That individual calls the item adware and recommends that you run MalwareBytes .  That software has a free version:  https://www.malwarebytes.com/mwb-download

FYI: I have the paid version of that software, myself.  It runs in the background to protect against unwanted or dangerous items that can try to get into the PC.  Very good protection in addition to anti-virus software.
