Scheduled Live Updates Fail 50% of the Time

Hi there,

 

I've got Norton Internet Security for Mac. I'm running it on a MacBook Pro 17" (Early 2008) w. a 2.6 GHz processor.

 

LiveUpdate fails more than 50% of the scheduled updates. This only relates to automatic, scheduled updates, manual updates always work fine.

 

How do I rectify this?

 

I've already tried the following TS:

 

Removal of all User Specific and System Wide plists.

 

Best Regards

 

Steve
