Default samsung download

Every few days my phone is trying download something from Samsung. Not sure what it is as it only says samsung on pull down menu.
It seems to get hung up first it stopped at 45% then it stopped at 71%. I try and find out what it is but can't seem to see anything that needs updating. My phone is rooted and I was wondering if it is trying to download the new OS kitkat. I press the X to stop it but that does not seem to do anything. When I restart my phone it goes away.I am using the original OS? Has anyone had the same thing happen recently? If so how do I fix this?
