Question about where to get free antivirus/spyware programs?

I need some really good free antivirus/spyware programs that won't hurt my computer to use. I think I have a virus and I know I have some kind of spyware, both of which have really affected my computer. Is there any such thing as good free programs for either and where could I get them if there are.
