Short description of Spyware Inoculator 2.0: 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.
