I download the 30-day trial of Norton Utilities to give it a spin and see if it was any good. I've unfortunately run into a problem pretty much straight away.
I've tried running the registry cleaner twice now and both times it has crashed towards the end of scanning with a "Not Responding" error from Windows.
