After a few days of somewhat large liveupdate download sizes, suddenly,
129.82 MB LiveUpdate size, only 3 update items:
Norton 2011 Virus Definitions - FAILED.
Norton Web protection Definitions - OK
Norton Pulse Updates - OK
Try again: Two small items total less than half MB,
Virus Definitions - OK
Pulse Updates - OK.
These two took at least 5 minutes to install, but "OK".
Everything else seems normal.
Windows XP, sp3, Norton Internet Security version 18.7.0.13
