Is my Norton Security Premium broken?

Basically, I would like to know for sure whether my Norton was updated correctly.

What happened was, I tried to update, and for whatever reason, after downloading the update Norton was taking forever to apply the update. I cancelled the update, but Norton was also taking forever to cancel.
 

I left it cancelling til the next day. When I came back, not only did Norton not finish cancelling the update, my computer froze. I had to force a restart.

I clicked 'Live Update' and Norton proceeded to download and apply the update I cancelled smoothly. I scanned a few small files and it worked. However, I'm afraid that the patch was not installed correctly due to me forcing a restart while Norton was still trying to cancel.

How can I know for sure that my Norton is whole?

Thanks.
