Ever since my husband downloaded Rosetta Stone to my computer, it's been running extremely slow. I want to delete the entire download since he isn't using it. How do I delete it permanently?

My computer is running very slow ever since my husband downloaded Rosetta Stone to it. I would like to permanently delete this program and do not know how to do this. Also, I've attached a copy of the results from EtreCheck scanning my computer. Can you please help me fix the issues EtreCheck found so that this too can help make my computer to run smoothly. Thank you
