Q: I have downloaded this program and am considering buying the extensive one.
A: I'm going to guess that you mean SuperAntiSpyware instead of "superspyware." Superantispyware, in my opinion, is the best free spyware removal program being offered today. I've used it for over a year and depend on it to get the crap off my computer. I use it weekly. But I do not see why you would consider buying the commercial version when the free home version is just as good, and made for home computers.
