Hmm, I can't seem to find that on my Tmo N2 but even if I did I don't think you could disable it. What version are you currently on?
You could try the following:
-A simple reset does wonders at times
-Find that program under application manager, force stop it and clear the cache while there. I don't think you'll be able to disable it. After doing so, monitor the phone but remember that if your going to perform a soft reset, do so before performing this second suggestion.
