Inoculate your PC to Prevent Spyware from ever being installed. While there are a few good Spyware removers wouldn't it be better to prevent Spyware from ever being installed in the first place? Spyware Inoculator's "Set it and Forget it" feature accomplishes just that. Most Spyware is installed over the Internet by using ActiveX Controls which are basically the same thing as a web site running a program (.exe) from their site on your PC.
