Just wondering which of the two programs you think are better? I noticed that Spysweeper has more options to configure, but I've also read alot of great reviews about SAS.
I would say Spysweeper is better the best Spyware program I've ever used is STOPzillia so you might check it out http://www.stopzilla.com/products/stopzilla/download-nonav.do
I use SAS and Malwarebytes Antimalware...I haven't seen anything get by them or be unable to be removed by them.
I use AVG Anti spyware and it has detected many backdoors. I highly recommend it. Its scanner is also fast and easy to use. I will never use norton now because it slows down my system and it missed so many pieces of spyware.
