SpywareBlaster doesn't scan and clean for spyware - it prevents it from ever being installed. How? By setting a "kill bit" for the CLSIDs of spyware ActiveX controls, it prevents the installation of any of them from a webpage. You can run Internet Explorer with Active-X enabled, but you will never even get a "Yes/No" box popped up, asking you to install a spyware Active-X control (Internet Explorer will never download or run it!). All other Active-X controls or plug-ins will work fine. The SpywareBlaster database contains information on these known spyware Active-X controls. Make sure you run the Check For Updates feature frequently to get the latest database! (And make sure you check the new items to protect your system against them!) As a side benefit, setting this "kill bit" will also prevent the spyware Active-X from running, in many cases, if it is already installed on your system.....(free).....
