Liveupdate aint updating...

[hyperion916]

I cant install a update for Norton System Works because the file it will replace is being used by norton. I alt ctrl del and tried to end the norton processes, but they wont end. I went to safe mode and ran Liveupdate and it still gets the same error. I checked the processes and none of the norton software is running...

This is the error I get:
LU1821: This update failed because it tried to overwrite a file that was in use. Close all of your Symantec applications and run LiveUpdate again.

What do I need to do to get the update to install?
