How to uninstall Illustrator and other adobe apps without login to Adobe Creative Cloud?

I installed Illustrator and other Adobe programs when I worked in a university.

Now I moved to anther university, and hardly use these apps. I am trying to uninstall these, because I am suspicious that some "update notification" app is running, which cause my computer run continuously and make noisy fan.

Problem is that when I try to uninstall these apps, a window pops up and tell me to log in Adobe Creative Cloud. This requires my old email address, which has been closed after I moved to another university. Please let me know how to uninstall Abobe apps without log in to Adobe Creative Cloud,
