Scheduling Norton Antivirus updates?

Is there a way to schedule antivirus updates to only run during the night?

It's a bit petty, but occasionally when I'm playing a game on Pogo, and have a timer to beat, my antivirus decides to update, slogging down the computer, causing me to blow that level of the game. It's annoying! The settings area seems to only allow turning on or off.

I have basic antivirus protection, up to date, copyrighted 2006.

go to control panel, symantec live update, and select automatic liveupdate, then configure when you want it to check for updates.
