LiveUpdate loop: endlessly requires you to restart your computer

OS 10.5.7 Internet Security 4 for Mac.

 

Problem started last night. Continued through this a.m.  At first it was a microdefs error that the NCO for Macintosh Anti-Phishing def's wouldn't update. After doing some internet searching I found and delted the latest LUcw MicroDefsB SymAllLanguages file which took off that alert and the red - infront of the NCO for Macintosh Anti-Phishing def's and NAV for Macintosh Virus def's in the summary of installed updates.

 

But at the bottom LU said I should restart, which I did. But after restarting and running LU->Customize This Update Session the window that opens shows green check marks on all items, but still demands a restart.

 

This is looping endlessly now 

 

What's up with that?
