Tried this a while back (<a href="http://news.ycombinator.com/item?id=629493" rel="nofollow">http://news.ycombinator.com/item?id=629493</a>), never worked for me (even on Windows), but then trying to get rid of background process SpoonSandbox.exe was worse than cleaning a virus. It just kept coming back, uninstall didn't do anything...
