|By "spybot", I assume that you mean 'Spybot Search and Destroy 1.4'.|
In settings you will find 'Ignore Products', find the entry you wish to allow and place a check in the box. Spybot will no longer look for it.
Another aproach is to run a scan, on the results page, right click the file and choose add to ignore list or something similar. I don't have any scumware on my computer to try it.
