"...MASetupCleaner runs once, on reboot after removing KIES, to remove any remnants of the MarkAny 'content safer' service, and is probably safe..."
WOW! Do you work for Samsung?
DOH! sorry, don't mean to be offensive...
...that is unless you work for or sell Samsung products.
This excerpt just reinforces what I said in this thread. If Samsung has to run more software to remove other software, they really do suck. If it is true, they should tell you when you uninstall the gak that more gak wants to run at the next start to look for old gak to remove. Sounds more like a secret spy to replace the one you just removed.
Good Luck.
