What are signs of parental monitoring computer software?

What are signs of computer monitoring software, like parental monitoring?
What are signs to look for to know if your computer has monitoring software, like screenshot programs to track activity? Most of these programs are made to be undetectable so what are folders to look in/tells that it has been installed on your computer? Will all programs be listed in the “add or remove programs” panel or is it possible to make some not show up? I need answers to all these questions, thanks so much if you can help. Will give best answer!

search add or remove programs. it has to be on their. it is impossible for it to go undetected. check documents and my computer. check all folders in their.
