Symantec Error Reporting

 OK, apologies in advance for this being a daft question but I have no idea at all about this stuff.

  Normally when I click the Norton icon on my computer it comes up with various options such as backup, run scans etc but every time I've clicked it today, instead of that coming up my screen goes dull and a warning comes up asking if I want to let Symantec Error Reporting make changes to my device.  I'm pretty sure that's just Norton updating itself or something but years ago I destroyed my mother's computer by messing around with it and it's made me paranoid!

  Is allowing this thing to make changes ok (and is there somewhere reliable I can read up on this stuff so I can avoid having to ask such stupid questions in future?)

  Much obliged for any answers!
