Running Windows 7. Uninstalled Kies yesterday. Booted up Today and I was prompted to allow MASetupCleaner to run. Found it in C:\Windows\SysWOW64 and removed it (shoot first ...).
Looking at the other files there with the names starting with MA, several had similar details copyrights ca. 2004, Korean language, and company details in Korean characters. "MA" apparently stands for MarkAny, which is a digital rights management company. It appears this is for combating music piracy and is associated with Samsung Kies.
I suspect that this was going to uninstall the MA software, and the fact that it was started after I rebooted was just a consequence of sloppy uninstall programming. Of course I don't know that, it could have been installing something that would have remained resident on my machine after Kies was uninstalled.
