iMac (late 2025) running very slow -- is there a way to improve the performance?

" Antivirus software: CleanMyMac, McAfee"

if it was me then I would remove those 2

and if Malwarebytes is the paid one which runs all the time then I would replace it with the free one that only use resources when you start it to scan every other day.

Your EtreCheck report shows the file. It is at /Library/Application Support/McAfee

However, that's the only McAfee file you have. I should remove that "menulet" file from EtreCheck's AV detection. That file alone is not sufficient to say you've got McAfee installed.

Get Find Any File...

Hold Option or alt key when selecting Find to Find All.

Find All for Name>Contains>mcafee & trash & reboot.
