NIS 2011 and Error Code 3035,6

Upon update from NIS 2010 to 2011, I have had trouble with the install.  I have Windows XP,  and windows firewall is turned off when installing/running Norton.

 

Error Code 3035,6 ...and a warning box saying antivirus protection has been turned off.

 

A run down of what I have tried:

I have, ran live update until no more udates found.  Restarted the computer.

Removed Norton program via Control Panel, Add/Remove.

Restarted.

Ran Norton Removal Tool.

Restarted.

Downloaded NIS 2011 again and installed.

Everything seems to run fine for a few minutes, then the same error code pops up.

Repeated the Live Update process and restarted.  Same error message on startup.

 

Please help!  I appreciate any advice you can give.
