Constant hard drive access in WinXP

Using FileMon, I see that csrss.exe and Norton's Aluscheduler (Live Update) are constantly access the hard drive. And I mean CONSTANTLY! The HD LED is always lit up and flashing. If it does stop, it's for less than 2 seconds and then it starts up again. I'm not sure what csrss.exe does, but I know it's an important Windows service. But why is it (and Aluscheduler) accessing the drive all the time? I know something is amiss somewhere, because I've seen plenty of PC's with both of these files running, and they don't have continuous hard drive activity..... Any help or suggestions will be appreciated.

Please, need help w/ this... it's making the PC mega-slow....

 

It could be as simple as disabling automatic live update in Norton, to see if the problem goes away. I suspect Norton has been corrupted & may require reinstall.

 

I had to use the Norton Product Remover to completely wipe out all the Norton crap-ola on the PC: Internet Security, System Works, Go Back, Norton Utilities.... what a difference!!! But the PC is still having internet connection trouble: a topic for a different thread....
