wuauclt.exe runs every day for approx 1 hour!

Once everyday the Windows update process wuauclt.exe runs for almost 40 mins during which time the system is completely unresponsive. Is this normal? I'm running Windows XP service pack 3 and I've got Norton AntiVirus installed.

I've just done a complete search for "wuauclt.exe" on my system. I found four candidates. Here are their sizes and message digests:
