I used to have a Maxtor Shared Storage II network drive; it broke down long ago already. (Later I tried to recover some data from it, and partially succeeded, but haven't yet fully documented it on that question.)
Anyway, I just noticed there are still some lingering bits remaining of the (thourougly crappy) software that came with the Maxtor device: a background process called "MaxBack Engine".
I googled around a bit and found something related but not very useful:

Under /Applications I found "Maxtor EasyManage.app" which I used to use for controlling the drive, and showed it some "rm -rf". Before deleting, I noted that the bundle did contain "MaxBack Engine.app" under Content/Resources.
But still, after reboot, the "MaxBack Engine" process is back. I did notice though that it only appears when logging in with my usual user account; with another account it wasn't launched.
So, dear Mac gurus, what could I do about this pest? I guess I could fall back to some Unix hackery and write a cronjob that kills any process with that name, but obviously it'd be nicer to be able to clean up from my computer everything left behind by Maxtor's piece of software.
