Everybody mentioned how bad the product is

Download and run the Norton Removal Tool
http://service1.symantec.com/SUPPOR...pen&docid=2003120216280806&nsf=nav.nsf&view=0
Warning: The Norton Removal Tool uninstalls "all" Norton
2009/2008/2007/2006/2005/2004/2003 products installed on your PC.
If you use ACT! or WinFAX, back up those databases before you proceed.
So for example if you still have Ghost and System Works installed,
and you want to remove the last traces of Norton 360 not removed when
you uninstalled it via Add/Remove programs, this tool has the unfortunate
side effect of removing any and "all" other Symantec product installed
on your PC (Ghost, System Works, Etc) also.
If after running the "removal tool" you still get a reboot message
post back and I'll give you some other things to try.
Finally is you can return the product to the store where you
purchased 360 from and get your money back. There is a much
better Norton product named Norton NIS (2009 version). Buy
this and you will be better off.
