By apps do you mean all of the annoying helper processes like "AdobeIPCBroker" etc.? I can't stand those and haven't looked into any of them much in detail but I think that a lot of them are required for something. That's part of why I was suggesting to use the Adobe Uninstall app/feature because it should clean up all of the tag-alongs that came with a particular program. I think unfortunately the bulk of them come from the Cloud app itself.
The thing is they don't need to be running when you aren't using Adobe but the property list that launches them has made it's way into your /Library/Preferences or System Preferences or elsewhere and they are automatically launched at startup. A few might be removable under the Login Items area in System Preferences>Users but it's not much use. You can remove the plist files in the Terminal app, but it won't be easy.
I think many of the processes are required to use Adobe anything though. Since Cloud is a subscription-based software they have a lot of various mechanisms that make sure people pay.
I'd say leave them alone unless you are totally purging everything and starting fresh and re-installing and they still linger. If they are causing problems or using too much CPU, investigate in Activity Monitor and check the open files and folders tab when you click the information button for a process and see which program they were installed with.
Adobe uses literally thousands of scripts, executables, open source code, dynamic libraries and those type things that many times they themselves didn't create and many more they did which is why the downloads are so massive. That said there are legitimate security vulnerability that come with the territory that have been exploited (yes of Macs) so it's possible that's also an issue.
That reminds me, how's your internet connection? Do you have fast internet working while you are using Premiere Pro???? I totally forgot that this is super important. Like I said Adobe wants to make sure you pay and all of the software will literally stop itself and give priority to checking in with Adobe's servers every few minutes or so to make sure your subscription is up to date. Try either making sure your wifi is fast and functional or possibly turning off your Wifi/Intenet all together so it knows not to attempt the check. Connecting to a poor/nonfunctional wifi. network can cause major problems from my experience.
