Just wanted some sanity

Hi everyone, apologies if i am not explaining things well. I have a macbook pro with Sequoia 15.1.1 and iphone 14 pro max with 18.1.1 (that gets so hot). I am probably paranoid as I am not overly technical on the mac but I have been having issues with access to my machine (i lose rights to my home directory - downloads, etc) and have been installing things like Adobe Acrobat DC to the latest versions only to notice it seems to revert to an older version. I am no expert but I some logs mention MDM - i notice Classroom and Studentd running on my machine which i try to remove through terminal but am unable to due to the PID changing immediately (there are no visible profiles on in system report and i own the mac and bought from Apple). I have some kext running - obviously some are part of the OS but as i mentioned i am not an expert and perhaps crazy, I have open ports and connections locally and even if i run lsof -i in recovery mode offline i have what appears to be connections - instlogd to port 32376. When i run network scans on my home network I am seeing various ports open on my router, which change or disappear as soon as i dig into them or do another scan (i have blew out the Dlink and now have 2 devices on it only. Tonight i reinstalled yet again (after removing) nordvpn app and i grabbed the logs from the application and it is showing them in the future...it just worries me. below is the EtreCheck output in safe mode. I hate to be a burden and perhaps i am just paranoid but i would really appreciate any comment pos or neg in regards to the output. thank you as i so tired and grateful for any help. James
