Ali1, I think a good idea would be to check the guidelines that Spybot S&D uses to classify adware, spyware etc. Maybe this can give you a good idea on what one of the leading spyware/adware cleaners looks for in a program. While your intentions may be legit, you have to remember that you won't be generating any revenue if you get a bad rep and nobody downloads your free program, let alone invest in a paid version.
Personally, the minute I see anything that says "track" or "monitor" in the EULA, it's an almost instant red flag.
