It is part of Norton Security 2007, update system, if your CPU constantly has high usage because of this system you can try a program fix from Symantec ( which does work)

After an update with Norton antivirus, it runs in the background, hogging nearly all of the CPU for about 10-15mins. While it's doing this I can't realisticly do anything as the PC is just so slow. Task manager does not allow you to change the priority of Nortans processes either, which is extremly annoying.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
