I think its great to have a schedule program built into Spybot but then the only thing that would help would be instead of a button saying stop could you change it to Pause. When you talking about large Hard Drives every time you stop the process it all has to start again. Could I recommend may be a pause if not idle button. Something which can take note of the idle process and the spybot process so that if you need to use the machine it would pause the process of spybot or slow to a background speed. This would be such a benifit as the spybot process sometime takes up to 90% making it very slow to do much else on sower machines.
