I think this is the biggest update I've seen.
Why so big?
What is the version number of your Norton product, you can find this by clicking the Norton icon, click support, hover over, about, on the window that opens, the second line down is the version number.
Has your version changed since the update?
Hi, my version is Norton 360 22.214.171.124
I upgraded to the new 360 program version a few days ago, it was a 100MB download too, however this time, it was just an update of 117MB. I haven't noticed any major changes after the update.
When v21 was released the version was 126.96.36.199 and if your version number is 188.8.131.52 it may be an upgrade through an update.
That might be the case.
I was just worried for the size, being bigger than the actual newest program version.
Look in the log for this update may antivirus databases.
