Norton Security Suite question

I just got a new computer a week ago and installed Comcast's Norton Security Suite on it after uninstalled a trial of Norton Internet Security.  I checked with disk defrag a couple days ago and it appeared to open up and let me in, but now when I go to check and analyze the drive it tells me another utillity scheduled it and I must delete those settings.  Is Norton the program that did that?  I have no idea what other program it could be.

 

Windows 7, 6 Gigs of Ram, 1 TB hard drive

Norton Security Suite 5, Malwarebytes Pro

 

And games.  That is all I have downloaded to my computer.  It is not the games.  It would be funny if it were.  Thank you.
