I had the same thing on my phone. I work with someone who also has a galaxy s3. Its not on his. He is with Verizon, though, whereas I am a sprint customer. I did a hard factory reset and it is still there. I found it because I wanted to root my phone after an app I use stopped working after the Jelly Bean update (which I wish I could undo if someone knows how to return to the prior operating system). In preparing to root it I downloaded the samsung drivers for the phone to my computer but it still doesn't recognize my device. When I was looking into that issue one of the peices of advice was to insure there were no administrators enabled preventing the communication. When I checked my administrators, I found the source of discontention in this thread and my experience was the same... it will not allow me to deactivate it. I found this thread via google trying to find out what it was and how to ditch it. Not sure if it is a sprint thing, a jelly bean thing, or something else. Would like it gone though since I didn't put it there. Even more than that I would like to return to my prior OS so my apps would work again!
