Stop Norton 360 automatic reboot

I'v had this bugging me for quite a while, sometimes when I get back to the computer it seemed it decided to just spontaneously reboot. Due to luck and good timing I realized that it was norton 360 who had done an some scan and needed to restart the system, it prompts for a restart and if that request is ignored for some time it will force a restart. Its a real problem for me since I usually leave lots of stuff open and im not able to restore everything as it was when the comuter is restarted.

 

So how do I get this problem to go away? I realize that this is done for a good reason, but I want to decide when the reboot happens.
