I agree with foxy, once you have run it a few times without a problem you should be safe to turn off the restore option. It never really hurts to leave it on, I don't believe it uses a significant amout of resources. I have recently been using Bazooka spyware scanner, although it doesn't auto-remove any found spy/adware items it does give you a detailed explanation on manually removing each one. I've found that Bazooka finds things that S&D and AdAware miss, and if you're obsessive like me you can run all three ocassionally... then you'll be hard-pressed to find a surviving piece of malware on your system :-D
