That would seem to be part of the Windows operating system.
So you might want to be careful how much of that you copied to a backup..I think it was mentioned...a Plan could be to backup your user data and programs and then wipe the disk and reinstall windows and application programs.
If you have a lot of different software programs...you are talking about much work.
You could do this....have two computers...and segregate what you did with each...Have one that you never let access to the Internet ...which is where the bad stuff comes from and the other with access but very little or preferable none, of my important stuff on it.
A KVM switch will allow sharing of the keyboard mouse and monitor....between the two machines...
