MS Content Index Service - 100% CPU usa...

It is caused by MS Content Index Service 'cisvc'. It will not stay deleted. It reappears in less than 30 seconds. Seems to be an integral part of the Window OS?
I had the Windows Search installed and uninstalled it.
The ‘cisvc’ file remained along with four others 'cisvc' files all in different folders.

Rebooting Windows: loads and runs normally, then a bit later the 'cisvc' program activates the runs at 98% of the CPU usage. Task Manager goes to 100% and stays there. Commit Charge: less than 500M out of 3421M.

I have Win XP, 1.5GB Ram, SP3, Norton Internet Security 2009.
50% free Hard Drive space. It is currently using just 35% of my available RAM.
I just reinstalled the OS.
This is on a Gateway 6022GZ Laptop.

I can end the process in Task Manager every time I reboot, but that is something I do not want to have to do every time I restart my computer.

Got any ideas on how to deal with this problem?
