Adobe stuff in my Documents and Applications without me realising, should I be worried?

Two days ago, I deleted all of my old Adobe files. Last year, I downloaded free trials of Adobe stuff like Premiere Pro, and when, two days ago, I realised the files were still there, I deleted them. I have noticed just now that the following have come up in my documents, which I'm assuming can only be related to that:

I have also noticed that Adobe Creative Cloud and Adobe Media Encoder CC 2018 are still in my applications:

Are these legit or a virus? If they are viruses, how do I remove them? If it isn't, I'm guessing there isn't any point in keeping these, so should I just delete them?
