IE-SPYAD adds a long list of sites and domains associated with known advertisers, marketers, and crapware pushers to the Restricted sites zone of Internet Explorer. Once you merge this list of sites and domains into the Registry, the web sites for these companies will not be able to use cookies, ActiveX controls, Java applets, or scripting to compromise your privacy or your PC while you surf the Net. Nor will they be able to use your browser to push unwanted pop-ups, cookies, or auto-installing programs on your PC.

Please note that IE-SPYAD is not an ad blocker. It will not block standard banner ads in Internet Explorer. What this Restricted sites list of known advertisers and crapware pushers will do, however, is:
stop unwanted crapware from being installed behind your back via "drive-by-downloads";
prevent the hijacking of your home page and other key Internet Explorer settings;
shut down ActiveX, Java, and scripting, all of which can be employed to push obnoxious advertising on you and compromise your privacy and security;
block cookies, which can be used to monitor and track your travels around the Internet;
combat obnoxious script-based popups that clutter your screen and force unwanted advertising on you.
