This appeared on local computer club web site today.

Reports of trouble with some installations of Norton Antivirus (NAV) are circulating on security forums.  Users are receiving a message that Auto-Protect is unable to start, causing computers to have no real-time virus protection.



One club member has experienced the same problem.  I advised her to manually run Live Update from within Norton Antivirus and download and install all available updates.  One of those was a Common Client update, a critical component of NAV.  After a restart, her Windows XP Home system and Norton Antivirus now run properly.



It has been my experience that the modular design of Norton products periodically leads to trouble.  This occurs because modules rely upon others to work correctly and at times, not all modules update together.  This may leave incompatible module versions which can cause software failure.

Thanks Ned. I'll check it out when we get home. Both computers have the default installation/options, but maybe the higher speed and larger RAM of the notebook make it unnoticeable.
