Norton 360 Live Update question

Hello,

I was performing the Norton 360 Live Update as I was browsing on Google Chrome and while I was processing the update Norton 360 told me that the update was 1,000kb in size. I have never gotten Norton 360 updates of that size. This is on my Windows 7 laptop and it is Norton 360 version 21.6.0.32 and everything is up to date. Does anybody know why I would get an update this big? It was not the first update of the day and it was running for about 2 hours by itself before this large update came in. I had cancelled the update due to the fact that it was unusual and I wanted to get some opinions before trying the update again.

Thanks for the help!
