Does Norton upload anything?

I'm just asking, because last night firefox4 became sluggish.  I opened up task manage a checked what was going on.  Networking  showed that 10mb or so was being heavily uploaded.  I turned off internet access and reboot the system.  I logged back on to download NIS, SuperAntispayware, and Malwarebytes and the 10mb upload started again.  I've checked Norton log and didn't find anything out of the ordinary.

 

I can't remember if I started firefox but I do remember adobe PDF plug-in failed to load some PDFs from Seagate.  I'm kind of thinking that it might have been a crash report being sent.

 

It hasen't happened again yet and I've been on all day.
