Please help me delete Microsoft AutoUpdate
I've had this iMac since 2016. For the past 2 months, every time I turn on my computer, this Microsoft #%*! icon turns on, and the pop-up is at the middle of my screen. I don't have any Microsoft app that needs any update! This is not even one of the apps that I've marked "launch at login." So where did this come from? I have to quit it every time after I turn on my Mac. Any advice will be much appreciated.
iMac 27″, macOS 12.7
