anti spyware

I need a program that prevents, cleans and detects spyware on windows machines. I want it to be able to download the latest upgrades, have a feedback from clients, I want the clients to be able to send to me new strings so we can come up with upgrades. I do not know too much about this so i will rely on your experience. I also need it to be its own code, not taking from some other software. I have tried a lot of them and the software that I like is spyzooka.. so you can see a little of its functionality......... of course whatever we can improve the better... Again I am open to ideas.... Thank you very much!
