How can we get the protection with spyware remover and adaware remover with free download?

I had already opted for both sites and they are providing the solutions with pay option. But I am searching for free download option to help me for protecting my laptop as well as desktop. Unable to protect with the help of 50 $ payment option for every laptop n desktop.
