I actually had a loop in background that would kill -9 various services every few seconds until I finally got them all uninstalled.

If you can kill -9 it sounds like it could have been uninstalled?

You need to kill -9 the denial-of-service-causing services so you can actually interact with the system in order to delete them. (I used to have to do this with organizational Windows machines before I realized I could boot off a livecd and either rm -rf them, or just install a real operating system; I assume OSX/MBP is similar.)

If I select "unscheduled" will I have to fill a survey before I can reboot the machine?
